The pH of a solution is given by:

$\overline{){\mathbf{pH}}{\mathbf{=}}{\mathbf{-}}{\mathbf{log}}\mathbf{\left[}{\mathbf{H}}_{\mathbf{3}}{\mathbf{O}}^{\mathbf{+}}\mathbf{\right]}}$

I. HClO3 is a strong, monoprotic oxyacid.

• strong acids completely dissociate in water and that acids donate H+ to the base (water in this case).
• The dissociation of HClO3 is as follows:
HClO3(aq) + H2O(l)  H3O+(aq) + ClO3(aq)

###### Problem Details

Order the following three solutions from smallest to largest pH:

1. 0.20  M HClO3
2. 0.0030  M HNO3
3. 1.50  M HCl
