Effervescent salts (sometimes called effervescent powders) are a special type of bulk powders or granules containing sodium bicarbonate
Bicarbonate
In inorganic chemistry, bicarbonate is an intermediate form in the deprotonation of carbonic acid. It is a polyatomic anion with the chemical formula HCO⁻₃.
Citric acid
Citric acid is a weak organic acid that has the chemical formula C₆H₈O₇. It occurs naturally in citrus fruits. In biochemistry, it is an intermediate in the citric acid cycle, which occurs in the metabolism of all aerobic organisms.

What are Effervescent medicinal beverages?
Effervescent medicinal beverages date back to the late 1800s and originally arose to mask the taste of bitter waters taken as curatives, during the water cure craze of that era. In the 17th and 18th centuries, scientists began uncovering the chemical make-up and physiological benefits of various salts such as Glauber's salt and Epsom salts.
What is the use of effervescent powder?
They are commonly used with acidic agents to cause a reaction that produces carbon dioxide. The carbon dioxide leads to a fizzing of the effervescent powder. Effervescent tablets and powders are widely used to deliver medicines contained antacids, pain medications, and cough or cold medicines.
What are some of the examples of Efflorescent powder?
Efflorescent powders Some crystalline substances liberate water of crystallization wholly or partly on exposure to humid atmosphere or during trituration and thus become wet or liquefy. Example of such substances include caffeine, citric acid, ferrous sulphate etc.
What is an effervescent solution?
Introduction. Effervescent tablets were designed to produce solutions that release carbon dioxide simultaneously. Usually, these tablets are prepared by compressing the active ingredients with mixture of sodium bicarbonate and organic acids such as citric and tartaric acid.
Which is a common ingredient of effervescent powder?
Sodium bicarbonateSodium bicarbonate, NaHCO3, is a common ingredient in effervescent powders and tablets. It is used with an acidic agent, such as citric or tartaric acid, to cause a reaction that produces carbon dioxide (CO2). The carbon dioxide leads to the resultant fizzing of the effervescent powder, such as seen with Alka-Seltzer.
What is the difference between efflorescence and effervescence?
The key difference between effervescence and efflorescence is that effervescence is the escape of gases from an aqueous solution causing the formation of foam or fizzing whereas efflorescence is the migration of a salt to the surface of a porous material where it tends to form a coating.
What is efflorescence give two examples?
(a) Efflorescence is the property of some substances to lose wholly, or partly their water of crystallization when their crystals are exposed to dry air even for a short time. Examples are: Washing soda, Glauber's salt, Epsom salt.

What Causes Efflorescence?
You may notice efflorescence both indoors and outside, and it can vary in frequency and intensity throughout the country due to moisture and temperature. Three conditions need to exist for efflorescence to occur:
How to Spot Efflorescence
Understanding the differences between efflorescence and stains is critical. Stains usually come in various colors but may appear similar to efflorescence at first. Efflorescence is a white, powdery substance that can be found on unsealed surfaces, including:
Preventing Efflorescence
Taking care of building materials before, during and after the construction process can help prevent efflorescence. To keep a building in it’s best condition, consider taking some precautions. There are many solutions to prevent efflorescence, including:
Ways to Troubleshoot Efflorescence
When efflorescence does occur, it’s important that you’re able to troubleshoot and know what to assess to help determine the possible reason behind it. Determining this will help you decide how to remedy the situation. Consider the following when efflorescence is detected on a building:
How to Remove Efflorescence
Luckily, there are some efflorescence remover techniques and home remedies you can try. Removing efflorescence can be quick and simple. In fact, efflorescing salts are water-soluble, which means efflorescence may disappear on its own due to normal weathering. Some of the best ways to remove efflorescence include:

What is the white powdery substance on the surface of unsealed concrete?
Efflorescence is the white powdery substance on the surfaces of unsealed concrete and the white blush seen with sealed floors. Efflorescence is caused by vapor migrating through the slab bringing soluble salts to the surface of the concrete. Efflorescence is normally worn off or washed away on unsealed concrete surfaces.
What is the purpose of a protimeter moisture probe?
More accurate, but also more expensive, testing technology such as the Protimeter Moisture Measurement System (ASTM Standard F-2170-02) uses a probe to measure the presence of moisture on and below the concrete surface along with the relative humidity, dew point and temperature.
What is the most prudent course of action?
The most prudent course of action includes stripping the sealer in order to conduct a test to determine the rate of vapor transfer and then develop a remedial strategy. It is important to get it right the second time so take time to diagnosis the causes as best you can with the information available.
Why does my concrete floor have white eflorescence?
White efflorescence caused by high water movement pushing salts out of a concrete floor slab. Answer: It sounds like you have a chronic efflorescence problem. Efflorescence is a process where salts leach out of the concrete, carried by water, and end up on the surface as a white dusty residue.
What makes black concrete grayish white?
Deposits of efflorescence make black concrete look grayish-white. Answer: This is one of the most common but least understood phenomenons with concrete. Efflorescence is a chalky white salt residue that can occur with any product containing cement.
Can concrete be placed on a vapor retarder?
The case can be made for placing the concrete directly on the vapor retarder or over granular material on top of the vapor retarder. The argument against the granular material is that it may become a saturated "blotter" before the slab is poured adding even more water that has only one way to leave.
What chemicals are used to seal concrete floors?
The chemicals include silicates, silicaonates, polysiliconates, sila nes, siloxanes and the new lithiums, to name a few. Some of these are used in the conjunction with polished concrete floors. Some are used on floors already acid stained or dye stained and could receive a membrane type sealer.
a. Heat method
This method requires blending of all the components, with 15% – 20% of the acid ingredients as citric acid monohydrate, and heating on a bath (about 100 C). The mole of water released from citric acid during heating moistens the powder, and granules are formed from this moistened powder mass.
b. Wet method
The citric acid is moistened and added to sodium bicarbonate. Granules are then formed from this partially fused mass, using a suitable granulator.
What is an effervescent tablet?
Effervescent or carbon tablets are tablets which are designed to dissolve in water, and release carbon dioxide. They are products of compression of component ingredients in the form of powders into a dense mass, which is packaged in blister pack, or with a hermetically sealed package with incorporated desiccant in the cap. To use them, they are dropped into water to make a solution. The powdered ingredients are also packaged and sold as effervescent powders or may be granulated and sold as effervescent granules. Generally powdered ingredients are first granularized before being made into tablets.
When were effervescent drinks invented?
Generally powdered ingredients are first granularized before being made into tablets. Effervescent medicinal beverages date back to the late 1800s and originally arose to mask the taste of bitter waters taken as curatives, during the water cure craze of that era.
Which active ingredients are most effective in effervescent preparations?
