Aqueous solution of barium phosphate whi...

Aqueous solution of barium phosphate which is `100%`ionised has `DeltaT_(f)//K_(f)`as 0.05.Hence ,given solution is

A

0.01 molal

B

0.02 molal

C

0.04 molal

D

0.05 molal

Text Solution

Verified by Experts

The correct Answer is:
A
`Ba_(3)(PO_(4))_(2)hArr 3Ba^(2+)+2PO_(4)^(3-)`
value of i=`5(100%ionised)`
so`DeltaT_(f)=ik_(f)m`
so m =`(cancel(O)T_(f))/(ik_(f))=(0.05)/(5)=0.01`
