WebGoal: Write the expression for the dissociation constant of a weak acid or weak base. Summary: In water, weak acids and weak bases produce only a few ions when equilibrium is reached. Weak acids have small K a values, whereas strong acids, which are essentially 100% dissociated, have very large K a values. The reaction for a weak acid can be ...
