Question

Define the acidity of a base. What is the acidity of ammonium hydroxide, magnesium hydroxide, and aluminium hydroxide?

Answer 1

Acidity of a base is defined as the number of hydroxide ions given by a base in aqueous solution.

Acidity of ammonium hydroxide$\left(N{H}_{4}OH\right)$ is 1.

Acidity of magnesium hydroxide$\left[Mg{\left(OH\right)}_2\right]$ is 2.

Acidity of aluminium hydroxide $\left[Al{\left(OH\right)}_3\right]$ is 3.
