**HClO _{4} **→ 3 more Oxygen than Hydrogen → strong acid

Calculate H^{+}:

$\mathbf{3}\mathbf{.}\mathbf{0}\mathbf{}\mathbf{M}\mathbf{}\overline{){\mathbf{HClO}}_{\mathbf{4}}}\left(\frac{1\overline{)\mathrm{mol}}{H}^{+}}{1\overline{)\mathrm{mol}{\mathrm{HClO}}_{4}}}\right)\mathbf{=}$**3.0 M H**^{+}

What is the pH of a 3.0 M solution of HClO_{4}?
