The H3o+ concentration of a solution is found to e 3.40*10^-6. What is the pH of the solution? what is the H3O+ concentration? what is the OH- concentration? is this and acidor a base?

• chemistry -

pH = -log(H3O^+)
(H3O^+) = 3.40E-6
(H3O^+) + (OH^-) = Kw = 1E-14. You know Kw and (H3O^+); solve for (OH^-).
