What is the pOH of an aqueous solution at 25.0 °C in which [H+] is 0.0020 M?
7.79
-11.30
-7.79
11.30
none of the above

Answer 1

pOH + pH = 14

calculate pH and subtract from "14"

Answer 2

pH = -log (base 10) [H+]

Answer 3

so, substitute for the concentration og H+ and find pH first.

Answer 4

Thank you! I figured it out. It was 11.3

Answer 5

good for you.
