Find the pH and the pOH of the solution

1. 0.023 M solution of perchloric acid

2. 6.6 x 10^-6 M solution of nitric acid

3. 0.0334 M solution of potassium hydroxide

Ok so the PH for each solution will be

1.) 1.638 2.) 5.2 3.) 12.524

This is found using the formula: pH = - log [H 3O+].

And the pOh for each one will be

1.) 12.362 2.) 8.8 3.) 1.4763

This is found by the formula pOH = - log10[OH - ]

Hope this is useful
