Out of three 1.0 m solutions of glucose (CH120s), sodium sulfate and ammonium phosphate which will have the highest boiling point, lowest freezing point, and lowest vapor pressure?Explanation / Answer
as number of solute particles increase in the solution boiling point will increase , vapour pressure decrease and freezing point will decrease.
in above solutions
C6H12O6 will not dissociate.
Na2SO4 gives three ions in solution (2Na+ and SO4-2)
(NH4)3PO4 gives four ions 3 NH4+ and 1 PO4-3.
so ammonium phosphate gives more particles in solution. it have high boiling point , less vapour pressure and less freezing point among the given solutions.
