Then, use the formula pH = -log10[H3O+], … WebJun 17, 2024 · So we know that the [H3O +] is 5.00 x 10-13. This very tiny number makes sense for a basic solution. If a solution is basic, the [H3O +] will be tiny compared to the [OH-]. And our H 3 O + concentration (5.00 x 10-13) is tiny compared to the OH-concentration (2.0 x 10-2). Remember that the correct unit for concentration is M.
