Answer:
Types of Bases
A strong base dissociates entirely into its ions in water or is a compound that can remove a proton (H+) from a weak acid. Examples of strong bases include potassium hydroxide (KOH) and sodium hydroxide (NaOH). A weak base incompletely dissociates in water.
Types of Bases
Strong base – It is a compound that has an ability to remove a proton from a very weak acid. Or they completely dissociate into its ions when in water. Examples are potassium hydroxide (KOH), sodium hydroxide (NaOH).
Weak base – There is incomplete dissociation when in water. The aqueous solution contains both the weak base as well as its conjugate acid. Examples are ammonia (NH3), water (H2O), pyridine (C5H5N)
Superbase – These bases are better at deprotonation when compared to a strong base. These have very weak conjugate acids. They can be obtained by mixing an alkali metal with its conjugate acid. It can’t sustain in aqueous solution as it is a stronger base than hydroxide ion. Examples are sodium hydride (NaH), ortho-diethynylbenzene dianion (C6H4(C2)2)2−
Neutral base – It forms a bond with a neutral acid share an electron pair.
Solid base – It is active in solid form. Examples are silicon dioxide and sodium hydroxide mounted on alumina.
