Base ionization

Definition

Base ionization is the process in which a base accepts protons from water molecules, producing hydroxide ions ($OH^-$) and the conjugate acid of the base. This reaction occurs in aqueous solutions.

5 Must Know Facts For Your Next Test

1. Bases ionize in water to produce hydroxide ions ($OH^-$).
2. The strength of a base is determined by its ability to ionize completely or partially.
3. Strong bases like $NaOH$ ionize almost completely in water, while weak bases like $NH_3$ ionize only partially.
4. The equilibrium constant for base ionization is called the base dissociation constant ($K_b$).
5. In Brønsted-Lowry theory, a base is defined as a proton acceptor.
