Find out the percentage dissociation of an acid having conc. of 10M\text{10}\text{M} and dissociation constant 1.0×10−31.0 \times 1{0}^{- 3}.

Options

  1. A0.1
  2. B0.5
  3. C1.0
  4. D2.0

Correct answer

C. 1.0

Step-by-step solution

α=10−310=10−2\alpha = \sqrt{\dfrac{1{0}^{- 3}}{10}} = 1{0}^{- 2}
%\alpha = 1{0}^{- 2} \times 100 = 1%
