Which of the following will decrease the pH of a 50 ml solution of `0.01 M HCI` ?

A

Addition of 5 ml of 1 M HCL

B

Addition of 50 ml of 0.01 M HCl

C

Addition of 50 mL of 0.002 M HCl

D

Addition of Mg

Text Solution

Verified by Experts

The correct Answer is:
A
Addition of 5ml of 1M HCl will decrease the pH, because only this will increase the `H^(+)` ion concentration in the solution.
