A strong base can be defined as a chemical compound that has the capacity to remove a proton from a molecule of even a very weak acid in an acid-base reaction. A strong base is that which has the ability to completely dissociate in an aqueous solution to yield one or more hydroxide ions per molecule of the base. A strong base reacts with strong acid to form stable compounds.
What are the three bases?
The word base has three different definitions in chemistry, and they are Arrhenius base, Bronsted base, and Lewis base. All the base definitions agree to the fact that bases react with acids.
What is the basic work of alkalis?
All alkalis are bases, but all bases are not alkalis, only the bases that dissolve in water are known as alkalis. The main work of a base is to neutralize an acid, but an alkali not only neutralizes the acids, but it also produces hydroxide ions. Alkalis are usually called the subset of bases. Bases never completely dissolve in water, but alkalis completely dissociate in water to produce hydroxide ions OH⁻.
What is a weak base?
A weak base can be defined as a chemical compound that does not fully dissociate in an aqueous solution , or it can be said that the protonation in a weak base is always incomplete. When a weak base is added to an aqueous solution, it does not ionise entirely as a result of which the aqueous solution still contains a large number of undissociated molecules of the base. Now below, we will list some weak base examples.

What is the Definition of a Base in Chemistry?
A base substance is typically a solution that has a pH level of more than 7. Bases react with acids to form salts during a neutralisation (or double replacement) reaction.
What Does a Base Do in Chemistry?
A base is very chemically reactive due to its charge imbalance. Depending on the type, a base has excess negatively charged ions when it’s dissolved in water. These excess ions tend to attract positively charged ions, particularly hydrogen ions from acids.
How to Identify a Base in Chemistry

All definitions agree that bases are substances which react with acids as originally proposed by G.-F. Rouelle in the mid- 18th century .
What is a base in acid?
In the more general Brønsted–Lowry acid–base theory (1923), a base is a substance that can accept hydrogen cations (H + )—otherwise known as protons. This does include aqueous hydroxides since OH − does react with H + to form water, so that Arrhenius bases are a subset of Brønsted bases.
Why can't superbases be kept in water?
They are called superbases, and it is impossible to keep them in water solution because they are stronger bases than the hydroxide ion. As such, they deprotonate conjugate acid water.

In chemistry, there are three definitions in common use of the word base, known as Arrhenius bases, Brønsted bases, and Lewis bases. All definitions agree that bases are substances which react with acids as originally proposed by G.-F.
What is the name of the substance that dissociates in aqueous solution to form hydroxide ions
Svante Arrhenius proposed in 1884 that a base is a substance which dissociates in aqueous solution to form hydroxide ions OH −. These ions can react with hydrogen ions (H + according to Arrhenius) from the dissociation of acids to form water in an acid–base reaction.
What is a strong base?
A strong base is a basic chemical compound that can remove a proton (H +) from (or deprotonate) a molecule of even a very weak acid (such as water) in an acid–base reaction. Common examples of strong bases include hydroxides of alkali metals and alkaline earth metals, like NaOH and Ca (OH)#N#2, respectively. Due to their low solubility, some bases, such as alkaline earth hydroxides, can be used when the solubility factor is not taken into account. One advantage of this low solubility is that "many antacids were suspensions of metal hydroxides such as aluminium hydroxide and magnesium hydroxide." These compounds have low solubility and have the ability to stop an increase in the concentration of the hydroxide ion, preventing the harm of the tissues in the mouth, oesophagus, and stomach. As the reaction continues and the salts dissolve, the stomach acid reacts with the hydroxide produced by the suspensions. Strong bases hydrolyze in water almost completely, resulting in the leveling effect ." In this process, the water molecule combines with a strong base, due to the water's amphoteric ability; and, a hydroxide ion is released. Very strong bases can even deprotonate very weakly acidic C–H groups in the absence of water. Here is a list of several strong bases:
What are the groups of salts that are stronger than bases?
Group 1 salts of carbanions, amides, and hydrides tend to be even stronger bases due to the extreme weakness of their conjugate acids, which are stable hydrocarbons, amines, and dihydrogen. Usually, these bases are created by adding pure alkali metals such as sodium into the conjugate acid. They are called superbases, and it is impossible to keep them in water solution because they are stronger bases than the hydroxide ion. As such, they deprotonate conjugate acid water. For example, the ethoxide ion (the conjugate base of ethanol) in the presence of water undergoes this reaction.

How to tell if something is an acid or base?
Mix water with a base and that water will play the part of the acid. Now the water molecules give up their own protons to the base and become what are known as hydroxide (Hy-DROX-ide) molecules. To gauge whether something is an acid or base, and how strong it is, chemists employ the pH scale. The strongest acids are at the lowest end of the scale.
How to tell if a base is acidic?

What is hydrogen atom?
A hydrogen atom consists of a proton (positively charged particle), around which an electron (negatively charged particle) orbits. According to the Brønsted-Lowry definition, molecules that are acidic have the capacity to give up — donate — that proton to another molecule. pikepicture/iStock/Getty Images Plus.
What is the simplest atom of an acid?
At a minimum, that tells us that all Brønsted-Lowry acids must contain hydrogen as one of their building blocks. Hydrogen, the simplest atom, is made up of one proton and one electron. When an acid gives away its proton, it hangs on to the hydrogen atom’s electron. This is why scientists sometimes call acids proton donors.

Properties
General properties of bases include:
• Concentrated or strong bases are caustic on organic matter and react violently with acidic substances.
• Aqueous solutions or molten bases dissociate in ions and conduct electricity.
• Reactions with indicators: bases turn red litmus paper blue, phenolphthalein pink, keep bromothymol blue in its natural colour of blue, and turn methyl orange-yellow.
Reactions between bases and water
The following reaction represents the general reaction between a base (B) and water to produce a conjugate acid (BH ) and a conjugate base (OH ):
B(aq) + H2O(l) ⇌ BH (aq) + OH (aq)
The equilibrium constant, Kb, for this reaction can be found using the following general equation:
Kb = [BH ][OH ]/[B]
Neutralization of acids
Bases react with acids to neutralize each other at a fast rate both in water and in alcohol. When dissolved in water, the strong base sodium hydroxide ionizes into hydroxide and sodium ions:

Lewis bases
A Lewis base or electron-pair donor is a molecule with one or more high-energy lone pairs of electrons which can be shared with a low-energy vacant orbital in an acceptor molecule to form an adduct. In addition to H , possible electron-pair acceptors (Lewis acids) include neutral molecules such as BF3 and high oxidation state metal ions such as Ag , Fe and Mn . Adducts involving metal ions are usually described as coordination complexes.
