Question

How many of the following salt(s) form basic solution when dissolved in water? ( NH 4)2 SO 4, KCl , CH 3 COONa , FeCl 3, NaBr, BaCl 2. (A)  (B)  (C)  (D)

Salts of weak acid and strong base give basic solution

(p H > 7)

.
Salts of weak acid and weak base gives basic solution, if

K_{b} > K_{a}

.

$(N H_{4})_{2} S O_{4}$	Strong acid	Weak base
$K Cl$	Strong acid	Strong base
$C H_{3} COON a$	Weak acid	Strong base
$F e C l_{3}$	Strong acid	Weak base
$N a B r$	Strong acid	Strong base
$B a C l_{2}$	Strong acid	Strong base

Only

C H_{3} COON a

forms basic solution when dissolved in water.
