Question #43444

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

a) 1x10^-5

b) 1x10^-9

c) 1x10^-3

d) 1x10^-12

Expert's answer

pH + pOH = 14

pH = 14 - pOH = 5

pH = -lg [H

[H

So, the correct option is (a): 1x10

pH = 14 - pOH = 5

pH = -lg [H

^{+}][H

^{+}] = 10^{-pH}= 1x10^{-5}So, the correct option is (a): 1x10

^{-5}
