You are watching: Which one of the following is a weak acid?
Weak acids and bases are just partly ionized in their options, whereas strong acids and bases are entirely ionized as soon as liquified in water. Some common weak acids and bases are provided here. Furthermore, weak acids and bases are incredibly prevalent, and we encounter them regularly both in the scholastic difficulties and in daily life. The ionization of weak acids and bases is a slrfc.orgical equilibrium phenomenon. The equilibrium values are important for the understanding of equilibria of weak acids and weak bases. In this link, you probably realize that conjugate acids of weak bases are weak acids and also conjugate bases of weak acids are weak bases.

Ionization of Weak Acids
Acetic acid, (ceCH3COOH), is a typical weak acid, and it is the ingredient of vinegar. It is partly ionized in its solution.
The structure of the acetate ion, (ceCH3COO-), is shown listed below.
