Which of the following aqueous solution has the higherst boiling point – InterviewSolution

1.	Which of the following aqueous solution has the higherst boiling point ?
Answer» `"0.1 M KNO"_(3)` `"0.1 M "Na_(3)PO_(4)` `0.1M BaCl_(2)` `.1 M K_(2)SO_(4)` Solution :Higher the CONCENTRATION of ions in the solution. Higher is the elevation in boiling point. As 0.1 M `Na_(3)PO_(4)`has highest concentration of ions, elevation of boiling point is highest for 0.1 M `Na_(3)PO_(4)` and so is the boiling point. ALTERNATIVELY, `DeltaT_(b)=iK_(b)m`. For the same VALUE of m, higher is the value of i, higher is `DeltaT_(b)`.
