Question

Which is a characteristic of weak acids and weak bases?

Ka and Kb values of weak acids and weak bases are small.
Forward reactions of weak acids and weak bases are favored.
Dissociation of weak acids and weak bases is nearly complete.
Many H+ or OH– ions are present in their solution.

Answer 1

The answer is A. Ka and Kb values of weak acids and weak bases are small.

Answer 2

Ka and Kb values of weak acids and weak bases are small.

This is because weak acids and weak bases do not dissociate completely, favoring the reactants more than dissociating into the product of H+ or OH-.
