The hydrogen ion concentration of a sample of orange juice is 2.0 X 10−11moldm−3. What is its pOH? [log102 = 0.3010]

A.

3.30

B.

13.00

C.

10.70

D.

11.30

View answer & explanation

Correct answer is A

PH+POH=14
pH = Log [H+]

p[H+ ] = 2.0 X 10−11moldm−3

  pH = Log [2.0 X 10−11]

  pH = 10.70

10.70+ pOH =14
pOH = 14 -10.70

= 3.30
