Question

Define each of the following with one example:

(c) Oxyacids

Answer 1

Acids:

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

Oxyacids:

• Acids containing oxygen, hydrogen, and one more element are called Oxyacids.
• For example, Nitric acid $\left({\mathrm{HNO}}_3\right)$.
• The majority of nonmetallic covalent oxides react with water to generate acidic oxides, and they react with water to form Oxyacids, which leads to the formation of Hydronium ions $\left({\mathrm{H}}_3{\mathrm{O}}^{+}\right)$ in solution.
• The chemical equation for the reaction of Nitric acid with water is as follows

${\mathrm{HNO}}_3\left(\mathrm{aq}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)\to {\mathrm{NO}}_3^{-}\left(\mathrm{aq}\right)+{\mathrm{H}}_3{\mathrm{O}}^{+}\left(\mathrm{aq}\right)$
