If the hydroxide ion [oh-] concentration of an aqueous solution is 1 x 10 -3 m, what is the [h+] in the solution? is the solution acidic, basic, or neutral?

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.
