Answer: The pH of the 0.02 M HCl solution is 2.

Step-by-step explanation:

The pH of the solution is defined as negative logarithm of hydrogen ion concentration in a solution.

$pH=-\log[H^+]$

The pH of the HCl solution of 0.01 Molar willbe :

$HCl(aq)\rightarrow H^+(aq)+Cl^-(aq)$

0.01 Molar of HCl will produce 0.01 M of
[H^+] ions.

[H^+]=0.01 M

$pH=-\log[H^+]=-\log[0.01]=2$

The pH of the 0.02 M HCl solution is 2.
