Question

Define each of the following with one example:

(a) Monobasic acids.

Answer 1

An acid is a substance in which the only positive ion is hydrogen.

A monobasic acid is a substance that produces only one hydrogen ion $\left({\mathrm{H}}^{+}\right)$ or contains only one replaceable hydrogen ion per molecule of the acid when completely dissociated in water. For example, Hydrochloric acid $\left(\mathrm{HCl}\right)$.

The chemical equation is as follows:

$\mathrm{HCl}\left(\mathrm{aq}\right)\rightleftharpoons {\mathrm{H}}^{+}\left(\mathrm{aq}\right)+{\mathrm{Cl}}^{-}\left(\mathrm{aq}\right)$
