Q18 / 60 · JEE Advanced 2014 (Paper 1) · Chemistry

$M X_{2}$ dissociates in $M^{2 +}$ and $X^{-}$ ions in an aqueous solution, with a degree of dissociation $(α)$ of 0.5. The ratio of the observed depression of freezing point of the aqueous solution to the value of the depression of freezing point in the absence of ionic dissociation is

Correct answer: 2

Hence, the correct answer is 2.
