The  pH  value  of  0.1  M  hydrochloric  acid  is approximately 1. The approximate pH value of 0.05 M sulphuric acid is most likely to be

A.0.05
B.1✓ Correct
C.0.5
D.2
Explanation

From the given conditions, we know that- eqm. 2 2 4 4 eqm. + HCl H Cl 0.1        0         0    t =0 0        0.1         0.1  t H SO 2H SO 0.05            0         0     t =0 0               0.1         0.1   t [H ]will have same ionic concenteration. So, the pH value of 0.05 M sulphuric acid will be equal to 1.
