pH= -log[H+]

pH= - log(0.01)= 2

To calculate the pH of an aqueous solution, the following formula is used:

pH = - Log [H+] Where,

pH = Concentration of hydrogen ion

H+ = Concentration of hydronium ion

In the question given above,

pH = ?

H+ = 0.01 M

pH = - Log [0.01]

Log 0.01 = -2

pH = - [-2] = 2.

Therefore, the pH of the HCl solution is 2. This implies that the solution is very acidic.
