#### Answer

The greater the value of $K_a$, the greater the acid strength. A strong acid almost completely ionizes in solution while a weak acid ionizes minimally in solution. As the strength of an acid increases, the strength of the conjugate base decreases. The greater the value of $K_b$, the greater the base strength. As the strength of a conjugate base increases, the strength of the conjugate acid decreases.

#### Work Step by Step

As an acid or base increases in strength, the strength of the conjugate acid or base decreases in strength. Furthermore, a greater $K$ value for an acid or base shows that the reaction is favored toward the right or toward the ionization of the acid. As a result, strong acids and bases almost completely ionize with a relatively large $K$ value.
