At room temperature, the product [H+] [OH-] in a solution is 10-14 moles/litre. If, [OH-] = 10-6 moles/litre, then the pH of the solution will be ________________________?
Correct answer: B. 8
- A. 6
- B. 8
- C. 10
- D. 12
Explanation
Using the ionic product, [H+][OH-]=10^-14, gives [H+]=10^-14/10^-6=10^-8 mol/L. Therefore pH=-log(10^-8)=8.
