JEE Mains · Chemistry · STD 12 -1. Solution and colligative properties
An aqueous solution of a salt \(MX_2\) at certain temperature has a van't Hoff factor of \(2\). The degree of dissociation for this solution of the salt is
- A \(0.50\)
- B \(0.33\)
- C \(0.67\)
- D \(0.80\)
Answer & Solution
Correct Answer
(A) \(0.50\)
Step-by-step Solution
Detailed explanation
\((a)\) Van't Hoff factore \((i)\) \(=\,\frac {No.\, of\, particles\, after \,association\, or \,dissociation}{No.\, of\, particles\, before\, association\, or \,dissociation}\) For \(M{X_2}\, \rightleftharpoons \,{M^{2 + }}\, + \,2{X^ - }\) \(t\,=\,0\) \(1\) \(0\) \(0\) at.eq.…
