# Problem: Calculate pH for each H3O+ concentrationa) [H3O+] = 1 x 10-8 Mb) [H3O+] = 0.1 Mc) [H3O+] = 1 x 10-12 M

###### FREE Expert Solution

Recall:

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

For a) [H3O+] = 1 × 10–8 M

= 8

The pH of the solution is 8.
