What is the pH of a 0.010 M HCl solution?

Explanation:
A strong acid like HCl dissociates completely in water, so the hydrogen ion concentration equals the acid concentration. The pH is the negative base-10 logarithm of that concentration. For 0.010 M HCl, the hydrogen ion concentration is 0.010 M. pH = -log10(0.010) = -log10(1.0 × 10^-2) = 2.00. Therefore, the pH is 2.00. A pH of 3.00 would require a concentration of 0.001 M, so that would be ten times less concentrated.
