A 010 M solution of which of the following salts is most bas

Solution

E) NaCN

let the acid be HA

let k is dissociation constant

k is smallest for HCN

k = [H+][A-]/[HA]

smaller value of k gives smaller value of [H+]

pH = -log10[H+]

smaller the value of [H+] larger is pH value which means smaller the [H+] less acidic is the acid hence its salt is most basic
