Question

if the hydroxide-ion concentration of an aqueous solution 1.0 x 10^-3 M, what is the [H+] in the solution? is the solution acidic, basic, or neutral?

Answer 1

The pH of a solution with a hydroxyl ion (OH-) concentration of 10−10 M is 4. This is because the pOH of such a solution is 10 since that is the negative logarithm of its OH- ion concentration.
