Answer:

C) 1 x 10-10 M

Explanation:

To solve this question we must use the equation:

Kw = [H+] [OH-]

Where Kw is the equilibrium dissociation of water = 1x10-14

[H+] is the molar concentration of hydronium ion = 1x10-4M

[OH-] is the molar concentration of hydroxyl ion

Replacing:

1x10-14= 1x10-4 [OH-]

[OH-] = 1x10-14 / 1x10-4M

[OH-] = 1x10-10 M

Right option is:

C) 1 x 10-10 M
