Question

which of the following has higher boiling point and why.-0.1M NaCl or 0.1M GLUCOSE

Answer 1

Perfectly answered Pradeep :
I need to tell Akhil
that
NaCl ------> Na+ + Cl-
Glucose is neutral so it doesn't ionise
Thus, i ( NaCl ) = 2
i(Glucose)= 1

Hence for the same molality or even molarty in wg of glucose and NaCl of both,
The elevation in boiling point for NaCl is more than glucose.

as,

Used formula
ΔT_b = iK_fm

Hence NaCl will have higher boiling point.
