What happens when you add a non volatile solute to a pure solvent?
Answer: When we add a non-volatile solute to a pure solvent, the vapour pressure of solution decreases, therefore, it is to be heated to higher temperature so that its vapour pressure becomes equal to the atmospheric pressure, i.e. its boiling point will be higher.
Which is the boiling point of trichloroacetic acid?
A 1.00 molal aqueous solution of trichloroacetic acid (CCl 3 COOH) is heated to its boiling point. The solution has the boiling point of 100.18°C. Determine the van’t Hoff factor for trichloroacetic acid. (K b for water = 0.512 K kg mol -1) (Delhi 2012)
