Question

Which one of these salts will form a basic solution on dissolving in water? Select one: a. MgCla b. KCN c. NaNO3 X d. NHANO3 e. Fe(NO3)3

Answer 1

KCN when dissolved in water will form HCN (is a weak acid). Some water H+ will associate with CN^- in KCN leaving excess OH^- ions and making the solution basic.

Option b is the right answer.

NaNO3 when dissolved in water, Na⁺ ions will form NaOH strong base and NO3^- will form HNO3 a strong base and the solution will be nuetral but not basic
