1758 - What are the ionization constants Ka and Kb of weak acids and bases?

Imagine you have a weak acid (like lemon juice or vinegar) or a weak base (like baking soda). These liquids can slightly break down into tiny particles in water.

Ionization constants are numbers that tell us how much of the acid or base breaks down. There are two main ionization constants:

  1. Ka (Acid Ionization Constant): For weak acids, Ka measures how easily the acid breaks down into tiny particles called ions. The higher the Ka value, the more the acid breaks down and the stronger it is.

  2. Kb (Base Ionization Constant): For weak bases, Kb measures how easily the base breaks down into ions. The higher the Kb value, the more the base breaks down and the stronger it is.

Think of it like this: Ka for acids and Kb for bases, both show how much they dissolve in water.
