उत्तर
Carbonic acid is a dibasic acid with two replaceable hydrogen ions; therefore it forms one acid salt or one normal salt.
\[\ce{H2CO^-3 + H2O -> \underset{Carbonate anion}{H3O+ + CO^2-_3}}\]
Hydrochloric acid is a monobasic acid with one replaceable hydrogen ion and so forms only one normal salt.
\[\ce{NaOH + HCl -> NaCl + H2O}\]
