Concept explainers
(a)
To determine:
Whether
EXPLAINATION:
Among 0.50 m sucrose and 0.35 m HNO3the freezing point depression in sucrose solution will be more than HNO3solution because of higher molal value.
So HNO3solution will have higher freezing point.
To determine:
Whether
EXPLAINATION:
While we compare 0.50 m sucrose and 0.35 m HNO3in terms of higher boiling Point, sucrose solution will be the one with higher boiling point, as Elevation in boiling point upon solute addition to pure solvent depends upon the molal value of solution. More the molality of solution more will be the elevation and hence more will be the boiling point of sth solution.
Sucrose solution will have more boiling point because of high molality value.
(c)
To determine:
Whether
EXPLAINATION:
By Raoult’s Law Vapour pressure the P?solventvalue will be same so the solution vapour pressure will depend Solely upon mole fraction of solvent i.e (??solvent)
.
Mole fraction of surose solution =
Where 55.6 is moles of water in solution.
Mole fraction of HNO3 solution =
As we see numerator value for HNO3solution is lesser than the other as a result of which the vapour pressure for nitric acid solution will be lower than HNO3
.
