Question

Is $\mathrm{KCl}$ an acid, base, or salt?

Answer 1

Solution:

1. Potassium chloride $\left(\mathrm{KCl}\right)$ is a neutral salt as it is formed by the reaction of a strong base and a strong acid.
2. Hence, its acidity is not affected by ions.
3. $\underset{\mathrm{Potassium}\mathrm{Hydroxide}}{\mathrm{KOH}\left(\mathrm{aq}\right)}+\underset{HydrogenChloride}{\mathrm{HCl}\left(\mathrm{l}\right)}\to \underset{\mathrm{Potassium}\mathrm{Chloride}}{\mathrm{KCl}\left(\mathrm{aq}\right)}+\underset{\mathrm{Water}}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}$
