Aluminium phosphate is 100% ionised in 0...

Aluminium phosphate is `100%` ionised in `0.01` molal aqueous solution . Hence , `DeltaT_(b) // K_(b)` is :

A

`0.01`

B

`0.015`

C

`0.0175`

D

`0.02`

Text Solution

Verified by Experts

The correct Answer is:
D
`AlPO_(4)hArrAl^(3)+PO_(4)^(3-)`
`i=1+x=2`
`DeltaT_(b)="molality"xxK_(b)xxi=0.01xxK_(b)xx2`
`:.(DeltaT_(b))/(K_(b))=0.02`
