How is chlorine produced?
A simple look at how chlorine is produced. Salt is dissolved in water to create a brine. Electricity is applied to the brine. Three products are produced: chlorine, caustic, soda, and hydrogen.
How does chlorine turn into a liquid?
By cooling the gas, the chlorine turns into a liquid, while the oxygen remains a gas, thus enabling its separation. This process is called liquefaction. Sodium hydroxide often contains leftover salt in the solution. The mixed sodium hydroxide and brine solution is heated to evaporate water.
Why are hydrogen ions and hydroxide ions present in the electrolytic cell?
Hydrogen ions and hydroxide ions are present due to the natural state of equilibrium of water. At the cathode, positive hydrogen ions gain electrons (reduction) and instantaneously covalently bond with itself to form H 2 gas that is removed from the electrolytic cell. The chemical equation is:
What happens when you contact an anode with chloride?
The positive charge of the anode attracts the negatively charged chloride ions. Upon contact with the anode, the chloride ions lose two electrons (oxidization).
Why is chlorine a common element?
Although it occurs naturally on earth, it exists chiefly in compounds, bound to other types of atoms such as sodium. Chlorine is highly reactive, so it bonds easily with other elements.
What is the most abundant source of chlorine?
Table salt is a key ingredient. One of the most abundant natural sources of chlorine is sodium chloride (NaCl), also known as table salt . Sodium chloride is very prevalent in ocean water and is also found in concentrated mineral deposits remaining from ancient oceans that have dried up over long periods of time.
What is the chemical reaction of chlorine?
This reaction occurs when electricity is applied to brine. The electricity rearranges the elements present in the brine, NaCl and H 2 O, and creates Cl 2, NaOH, and H 2. The chemical equation is:
How is chlorine made?
Most chlorine is manufactured electrolytically by the diaphragm, membrane, or mercury cell process. In each process, a salt solution (sodium or potassium chloride) is electrolyzed by the action of direct electric current which converts chloride ions to elemental chlorine.
Where is chlorine gas released?
Chlorine gas is evolved and released at the anode. The sodium ions are deposited along the surface of the flowing mercury cathode. The alkali metal dissolves in the mercury, forming a liquid amalgam. The amalgam flows by gravity from the electrolyzer to the carbon-filled decomposer, where deionized water is added.
How much sodium chloride is in the cell liquor?
Some chloride ions also migrate across the diaphragm resulting in the cell liquor containing about 16% sodium chloride. The cell liquor is typically concentrated to 50% sodium hydroxide by an evaporation process. The salt recovered in the evaporation process is returned to the brine system for reuse.
What is the cation selective process of the membranes?
The membranes are cation selective resulting in predominantly sodium ions and water migrating across the membranes to the cathode compartments. Water is reduced to form hydrogen gas and hydroxide ions at the cathodes. In the cathode compartment, hydroxide ions and sodium ions combine to form sodium hydroxide.
What is the product of a diaphragm cell?
The products of this type of cell are chlorine gas, hydrogen gas, and cell liquor composed of sodium hydroxide and sodium chloride solution. A nearly saturated sodium chloride solution (brine) enters the diaphragm cell anolyte compartment and flows through the diaphragm to the cathode section.
Where are chlorine and hydroxide ions produced?
Chloride ions are oxidized at the anode to produce chlorine gas. Hydrogen gas and hydroxide ions are produced at the cathode. Sodium ions migrate across the diaphragm from the anode compartment to the cathode side to produce cell liquor containing 10% to 12% sodium hydroxide.
What is membrane cell?
Membrane cell technology uses sheets of perfluorinated polymer ion exchange membranes to separate the anodes and cathodes within the electrolyzer. Ultra-pure brine is fed to the anode compartments, where chloride ions are oxidized to form chlorine gas.
How many gallons of water does a 3 inch chlorine tablet chlorinate?
One 3-inch chlorine tablet will chlorinate 5,000 gallons of pool water. You can calculate how many tablets you need for the size of your pool, place the tablets in the skimmer and let your pool filter distribute the chlorine along with the water returning to the pool. Use caution, however, when using this chlorination method.
Why do you need chlorine tablets for pools?
Chlorine tablets let you keep pool water clean with fewer water tests and adjustments. Chlorine is a chemical added to swimming pools to keep the water free of bacteria and algae. Chlorine levels in swimming pools vary, based on how much chlorine has already been used to remove bacteria and how much sunlight has broken down the chlorine molecules.
How do floating chlorinators work?
The theory is that you add chlorine tablets and let the floater move freely around your pool, slowly releasing chlorine as the pool water interacts with the tablets through holes in the bottom of the floater.
What is a chlorinator in a pool?
Tablet Chlorinators. Chlorine tablets are best used with tablet chlorinators. A chlorinator is a device installed as part of your pool's filtration system. When properly installed, the chlorinator is the last thing your pool water passes through before returning to the pool.
How does chlorine affect swimming pools?
Chlorine levels in swimming pools vary, based on how much chlorine has already been used to remove bacteria and how much sunlight has broken down the chlorine molecules. This means pool owners spend a lot of time testing and adjusting the levels of chlorine in their pools.
Can you leave chlorine tablets in a pool pump?
Use caution, however, when using this chlorination method. While the skimmer method works fine when the pump is running, you're headed for trouble if you leave chlorine tablets in your skimmer while the pool pump is off. The chlorine tablets are made to dissolve and will continue to do so whether your pool pump is running or not.
Can a floating chlorinator get stuck in a pool?
Floating chlorinators like this one can get stuck in your pool and cause damage. Image Credit: hookmedia/iStock/GettyImages. Some pool supply companies sell floating chlorinators, but these are not recommended. As their name suggests, floating chlorinators float on the top of your pool water.
Things to Consider
In the roundup above, we considered 5 of the best chlorine tablets for your pool right now. In this section, we will consider some of the important parameters that can affect your buying choice.
Types of Chlorine Tablets
On the market right now, you will find two main types of chlorine tablets. These are the stabilized chlorine tablets and the un-stabilized chlorine tablets.
Why Chlorine Tablets are better than other Chlorine forms
There are several reasons why using chlorine tablets is better than using other forms of chlorine, e.g., liquid or powder. In this section, we will consider these reasons.
Who should use Chlorine Tablets?
Pool chlorine tablets are a popular selection by swimmers and pool owners who know their worth. It is recommended for all type of people that are conscious of their pool safety and purity.
Features to Consider
Before making a purchase you should always consider the following features:
How to Use Chlorine Tablets
A really basic question that compels you to wonder why we can’t just throw them in the pool and let them do what they are supposed to.
What then is the best way to apply Chlorine Tablets?
A chlorinator usually works with your existing pump and filters and can be installed pretty easily. The best thing about using an automatic chlorinator is that it will ensure even distribution of chlorine across the entire body of water.
Floating Dispenser
Floating dispensers are small plastic containers you usually see on top of the water surface. Sometimes they have a strange duck or animal on top, and other times they are blue. The simplicity of floating dispensers is what makes them so appealing. They only retain a few tablets and keep them safely trapped until they dissolve gradually.
Skimmer
The skimmer in your pool is intended to keep loose surface detritus like leaves and bugs out. It’s also perfect for administering chlorine. Water floats into your skimmer line, past the pump, through the filter, through the heater, and back into the pool as your pool pump works.
Automatic Chlorinator
If you’re going to use chlorine tablets, an automatic chlorinator is the best way to go. This specialized piece of equipment allows you to manage how much chlorine is added to your water precisely. It also lets you choose how quickly or slowly your tablets dissolve.
Crushing the Tablets
Another way to add the chlorine tablets to the water is by crushing them. If you want to chlorinate your pool but are short on time, crushing a few tablets into a fine powder and scattering them over the pool is the best option.

Why do you need a chlorine dispenser in a pool?
What’s more, the high-concentrate chlorine may bleach the interior of the pool, so a dispenser prevents the pool from becoming discoloured.
Can you forget to add chlorine to pool?
However, some do find that a tablet-based solution can be problematic if you forget to add it once in a while, while others aren’t always happy with using chlorine tablets even when the pool won’t be in use.
Do you need a dispenser for chlorine tablets?
Because they’re smaller in consistency, as well as being less concentrated (around 60 per cent pure chlorine as opposed to 90 per cent in tablets) they dissolve more easily and don’t require you to put a dispenser in the pool, which some people find slightly unsightly.
Can you use chlorine tablets in tandem with granules?
For many, chlorine granules and tablets work well in tandem, but many will use the former at the start of a cleansing process as they can rid the pool of bacteria and algae much quicker than tablets.
How Is Chlorine Made?
The Chemical Reaction
- The chlorine manufacturing process, which includes industrial preparation and production of chlorine, sodium hydroxide, and hydrogen, involves a common chemical reaction known as electrolysis. This reaction occurs when electricity is applied to brine. The electricity rearranges the elements present in the brine, NaCl and H2O, and creates Cl2, NaOH, and H2. The chemical equation is: NaCl + H2O + electricity → NaOH + Cl2(g) + H2(g) Electrici…
Final Product Purification
- The electrolysis of brine does not completely convert the salt water to the final products. Depending on the specific conditions of the electrolytic cell, varying concentrations of oxygen, salt, and water are present in the final products. Chlorine gas is contaminated with oxygen that must be removed. By cooling the gas, the chlorine turns into a liquid, while the oxygen remains a gas, thus enabling its separation. This process is called liquefaction. So…
Producing Chlorine from Potassium Chloride
- How is chlorine made from other compounds? Sometimes, the salt used is not sodium chloride, but rather potassium chloride (KCl). When KCl is used, the resulting products are chlorine, potassium hydroxide (KOH), and hydrogen gas. Citation: Clark, J. (2019, June 5). The Manufacture of Chlorine. Retrieved from Chemistry LibreTexts
