Molal elevation constant `"K"_(b)` for water is `0.52K//m. 0.1` molal solution of `NaCl` will boil at

A

`100.52^(@)"C"`

B

`100.052^(@)"C"`

C

`101.04^(@)"C"`

D

`100.104^(@)"C"`

Text Solution

Verified by Experts

The correct Answer is:
D
If Van't Hoff factor is i, then
`Delta"T"_(b)=i"K"_(b).m("for NaCl i=2")`
`=2xx0.52xx0.1=0.104`
And, so the boiling point of solution will be `100.104^(@)"C".`
