Part 1 of 2:

Since [H3O+] = 10^-10 M, we can use the ion product of water to calculate the value of [OH-].

[H3O+][OH-] = 1.0 x 10^-14

10^-10 [OH-] = 1.0 x 10^-14

[OH-] = 1.0 x 10^-4 M

This solution is basic.

Part 2 of 2:

Since [H3O+] = 5.4 x 10^-7 M, we can use the ion product of water to calculate the value of [OH-].

[H3O+][OH-] = 1.0 x 10^-14

5.4 x 10^-7 [OH-] = 1.0 x 10^-14

[OH-] = 1.85 x 10^-8 M

This solution is basic.
