The pH of a chemical solution is given by the formula pH=log10[H+]\mathrm{pH}=-\log _{10}\left[\mathrm{H}^{+}\right] where [H+][\mathrm{H}^{+}] is the concentration of hydrogen ions in moles per liter. Values of pH range from 0 (acidic) to 14 (alkaline). What is the pH of a solution for which [H+]\left[\mathrm{H}^{+}\right] is 0.001?

Substitute the given value of [H+][H^+] in the given pHpH formula and solve for the value of pHpH.

pH=log10[0.001]=3\begin{aligned} pH &= -\log_{10} [0.001]\\ &= \boxed{3} \end{aligned}

Therefore, when [H+][H^+] is 0.0010.001, the pHpH of the solution is 33.
