Expert Answer

Step 1

(a)

The chemical formula of sulfuric acid is H2SO4. Hence, when a molecule of H2SO4 dissolves in an aqueous solution two H+ ions are produced as shown below.

Since each molecule generates two protons, sulfuric acid is diprotic. Therefore, the statement, “sulphuric acid is a monoprotic acid” is false.

Step 2

(b)

Weak acids are acids that dissociates partially into its corresponding ions in water or an aqueous solution. Whereas, strong acids completely gets dissociate into its corresponding ions.

HCl completely diss...
