You are watching: Which of the following is a weak base
Weak acids and bases are only partially ionized in their solutions, whereas strong acids and bases are completely ionized when dissolved in water. Some typical weak acids and bases are offered here. Furthermore, weak acids and bases are very common, and we conference them often both in the scholastic problems and in day-to-day life. The ionization that weak acids and also bases is a historicsweetsballroom.comical equilibrium phenomenon. The equilibrium ethics are crucial for the understanding of equilibria of weak acids and weak bases. In this connection, you most likely realize the conjugate acids of weak bases are weak acids and conjugate bases of weak acids space weak bases.

Ionization of Weak acids
Acetic acid, \(\ceCH3COOH\), is a usual weak acid, and also it is the ingredient that vinegar. The is partly ionized in that is solution.
\<\ceCH3COOH \rightleftharpoons CH3COO- + H+\>
The structure of the acetate ion, \(\ceCH3COO-\), is displayed below.
