pH = 11, The solution is Basic.

Explanation:

We know that;

[OH-] [H+] = 1 * 10^-14

we are given; [OH-] as 1 x 10^ - 3 M

Therefore, we can get the [H+] by;

[H+] = 1 * 10^-14/[OH-]

= 1 * 10^-14 M/1 x 10^ - 3 M

= 1 * 10^-11 M

But; pH = - log [H+]

Thus,

pH = - log (1 * 10^-11 M)

= 11

pH = 11, which means the solution is basic.
