Calculate the pH of each solution given the following [H3O+] or [OH -] values.

(a) [H3O+] = 1.5 10-8 M

1.0E-7 is what I got

(b) [H3O+] = 5.3 10-6 M

(c) [OH -] = 4.8 10-2 M

I get 7.0

(d) [OH -] = 9.0 10-3 M

Thank you.

(H3O^+) = 1.5E-8

pH = -log(H^+)

pH = -log(1.5E-8)

pH = -(-7.82)

pH = 7.82.
