314730 \({\rm{p}}{{\rm{K}}_{\rm{a}}}\) of a weak acid (HA) and \({\rm{p}}{{\rm{K}}_{\rm{b}}}\) of a weak base \((\mathrm{BOH})\) are 3.2 and 3.4, respectively. The \(\mathrm{pH}\) of their salt \((\mathrm{AB})\) solution is

314731 Assertion :
Aqueous solution of potassium cyanide is basic.
Reason :
Acidic or basic nature of a salt solution depends on the strength of the acid and the base forming it.
