Question

Fill in the blanks by using the correct word/ term given in the brackets.

HCl(aq) is a monoprotic acid. Therefore, ${\mathrm{CH}}_3\mathrm{COOH}\left(\mathrm{aq}\right)$ is a __ acid.

Answer 1

A monoprotic acid has the tendency to donate only a single atom of hydrogen or a single proton per molecule present in an aqueous solution.

Hydrochloric acid $\left(\mathrm{HCl}\right)$ is a monoprotic acid as it has only one proton available for donation. Similarly, Acetic acid also has only one proton available for donation because in an aqueous solution, it dissociates into acetate ions $\left({\mathrm{CH}}_3{\mathrm{COO}}^{-}\right)$ and hydrogen ions $\left({\mathrm{H}}^{+}\right)$.

Both of these acids give a single proton per molecule present in an aqueous solution.

HCl(aq) is a monoprotic acid. Therefore, ${\mathrm{CH}}_3\mathrm{COOH}\left(\mathrm{aq}\right)$ is a monoprotic acid.
