H3O+

[OH ]=

Answer 1

First, let's calculate the value of [OH-] using the ion product constant of water:

[H3O+] = 10^-5 M

Since [H3O+] * [OH-] = 1.0 x 10^-14 M^2

[OH-] = 1.0 x 10^-14 / 10^-5 = 1.0 x 10^-9 M

Therefore, [OH-] = 1.0 x 10^-9 M

This solution is neutral.

The correct number of significant figures for [OH-] is 2.
