Question

5.Consider mixing of equal volumes of each
solution mentioned in each pair below, in which
case pH of the resulting solution will be average
of the pH of solutions being mixed ?
(1) HCl (pH = 2) + NaOH (pH = 10)
(2) HCI (pH = 2) + HCl (pH = 4)
(3) HCI (pH = 2) + NaOH (pH = 12)
(4) CHCOOH (pH = 5) + NH, (pH = 10)
(K of acetic acid = K, of ammonia)​

Answer 1

Answer:

1)pH - 7

2)pH - 4

3)pH - 2

4)pH - 4
