Consider the salt NH4F in which the weak acid HF and the weak base NH4OH have different strengths 1 8 x 10 5 In such solutions since H OH the pH of such i e Ka of acid 7 2 x 10 4 and Kb solutions less than 7 acidic Case 3 If Ka Kb pH 7 Consider the salt NH4CN in which the weak acid HCN and the weak base NH4OH have differen strengths i e Ka of acid 4 0 x 10 10 and Kb 1 8 x 10 5 In such solutions since H OH hence t pH of such solutions more than 7 basic
