JEE Main Chemistry question
Statement 1: If a liquid solute more volatile than the solvent is added, the vapour pressure of the solution may increase, i.e. . Statement 2: In presence of a more volatile liquid solute, only the solute will form the vapour and the solvent will not.
Answer: (C)
Solution
When a liquid solute considerably more volatile than the solvent is added, its own vapour pressure contribution can make the total vapour pressure of the solution exceed that of the pure solvent (); Statement 1 is true. However,
