Classification of Bases
The various classification of the base is,
- Strong Bases
- Super Bases
- Weak Bases
- Lewis Bases
Strong Bases
In the acid-base reaction, a strong base is described as a basic chemical substance that can remove a proton (H+) from (or deprotonate) a molecule of even a relatively weak acid (like water). Hydroxides of alkaline earth metals and alkali metals, such as Ca(OH)2 and NaOH, are two common examples of strong bases.
For Example – Sodium hydroxide – NaOH, Lithium hydroxide – LiOH, and Potassium hydroxide – KOH.
Super Bases
Because their conjugate acids, amines, stable hydrocarbons, and dihydrogen, are extremely weak, Group 1 salts of hydrides, amides, and carbanions tend to be stronger bases. In general, these bases are made by mixing conjugate acid with pure alkali metals like sodium. They are known as superbases, and keeping them in water is nearly impossible because they are classified as stronger bases than the hydroxide ion. As a result, conjugate acid water is deprotonated.
For Example – Sodium hydride (NaH), Sodium amide (NaNH2), and Butyl lithium (n-C4H9Li).
Weak Bases
A weak base is one that does not completely ionize in an aqueous solution or one whose protonation is incomplete. At 25 °C, the equilibrium constant for the above-mentioned reaction is 1.8 x 10-5, implying that the degree of ionization or reaction is quite minimal.
Lewis Bases
A Lewis base, also known as an electron-pair donor, is a molecule that has a high-energy pair of electrons that can be shared with a low-energy empty orbital in an acceptor molecule to form an adduct.

Acids and Bases
An acid is a substance that is capable of donating a proton (hydrogen ion) to another substance. A base is a molecule able to donate OH- ion/strong>. Acidic substances are usually identified by their sour taste.
Acids have a sour taste and are corrosive i.e. exposure to acid on human skin can cause blisters. Some examples of acids are HCl, H2SO4, and others.
