Answer to Question #43444 in Physical Chemistry for ashley

Question

The pOH of a solution is found to be 9. What is the hydrogen ion ( H1+) concentration for this solution?

a) 1x10^-5

b) 1x10^-9

c) 1x10^-3

d) 1x10^-12

Answer 1

pH + pOH = 14
pH = 14 - pOH = 5
pH = -lg [H⁺]
[H⁺] = 10^-pH = 1x10^-5
So, the correct option is (a): 1x10^-5
