Which aqueous solution has minimum freezing point?

A

0.01 m NaCI

B

0.005 m `C_(2) H_(5) OH`

C

`0.005 m MgI_(2)`

D

`0.005 m MgS)_(4)`.

Text Solution

Verified by Experts

The correct Answer is:
A
`0.01 m NaCI equiv 0.02 m Na ^(+)` and `CI_(-)` ions which is maximum. Hence, depression in F. pt is max. or actual F. pt is minimum.
