The solution has a pH of 1.14


Since HCl is a strong acid, meaning that it completely ionizes when dissolved in water, the pH can be obtained directly from the concentration using the formula below:


Take the -logarithm of the concentration of hydronium ions that are in the solution:

#pH = -log (0.073M) = 1.14#
