For a weak electrolyte α 1 and α 2 are in ratio of 1 : 2, for a given concentration k a 1 = 2 × 1 0 - 4 . What will be value of k a 2 ?

Options

  1. A8 × 1 0 - 4
  2. B2 × 1 0 - 4
  3. C4 × 1 0 - 4
  4. D1 × 1 0 - 4

Correct answer

A. 8 × 1 0 - 4

Step-by-step solution

α 1 α 2 = k a 1 k a 2 1 2 = 2 × 1 0 - 4 k a 2 1 4 = 2 × 1 0 - 4 k a 2 k a 2 = 8 × 1 0 - 4
