- A \(1 \mathrm{~m}\) solution of magnesium sulphate
- B \(1 \mathrm{~m}\) solution of magnesium chloride
- C \(1 \mathrm{~m}\) solution of aluminium sulphate
- D \(1 \mathrm{~m}\) solution of aluminium chloride
Answer & Solution
Correct Answer
(A) \(1 \mathrm{~m}\) solution of magnesium sulphate
Step-by-step Solution
Detailed explanation
\(\Delta T_{b}=i K_{b} m\) Two solutions having same molality and same van' \(t\) Hoff factors will have same elevation in boiling points \(\left(\Delta T_{b}\right)\) and thus, have same boiling points \(\left(T_{b}\right)\). For NaCl,…
