Question

(a) The pH value of 10 M HCl solution is:
(1) 7
(ii) 6
(iii) 0
(iv) -6​

Answer 1

Answer:

In this problem, a 10 - 10 M solution of HCl contributes 10 - 10 M [H +]. The ionization of water contributes 10 - 7 M [H +]. The effective [H +] of this solution is 10 - 7 M and the pH=7.

1) is the right answer
