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.
