Answer the following questions :
Why the freezing point depression (`DeltaT_(f)`) of 0.4M NaCl solution is nearly twice than that of 0.4M glucose solution ?

Text Solution

Verified by Experts

Depression in freezing point `(DeltaT_(f))` is directly proportional to Van.t Hoff factor (i)
`DeltaT_(f) prop i`
In case of NaCl`" " i = 2`
In case of glucose, i = 1
Therefore, freezing point depression `(DeltaT_(f))` is nearly twice than that of glucose at same concentration (0.4 M).
