The pH of 0 . 01 N lime water is

Options

  1. A13 . 09
  2. B10
  3. C12
  4. D9 . 8

Correct answer

C. 12

Step-by-step solution

Lime water, Ca OH 2 , is strong base solution So, according to law of equivalence. OH - = N = 10 - 2   N pOH = - log OH - = - log 10 - 2 = 2 pH = 14 - pOH = 14 - 2 pH = 12
