What would be the pH of 0.00050 M HCl

pH = 3.30

Explanation:

Hydrochloric acid is a strong acid that completely dissociates in water.

For a 0.00050 M HCl solution the concentration of the hydrogen ions, [ H + ]

, is 0.00050 moles/liter (i. e. 0.025 M).

The pH is defined as - log [ H + ].

Substituting 0.00050 into the equation for pH we find that the 0.00050 M HCl solution has a pH of - log (0.00050) = 3.30.
