Question

Name an acid used (b) in an aerated drink.

Answer 1

Acids:

• An acid is a substance in which the only positive ion is hydrogen. It can replace by metal or basic radical.
• For example, Sulfuric acid $\left({\mathrm{H}}_2{\mathrm{SO}}_4\right)$ and Hydrochloride acid $\left(\mathrm{HCl}\right)$.

Aerated drink:

• Carbonic acid $\left({\mathrm{H}}_2{\mathrm{CO}}_3\right)$ is a weak acid.
• When Carbon dioxide $\left({\mathrm{CO}}_2\right)$is dissolved in aerated drinks, it results in the formation of carbonic acid.
• The equation is as follows:

${\mathrm{CO}}_2\left(\mathrm{g}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)\to {\mathrm{H}}_2{\mathrm{CO}}_3\left(\mathrm{aq}\right)$
