Question

Which aqueous solutions have highest boiling point 1]0.1m nacl 2]0.1m na2so4 3]0.1m urea 4] 0.1m glucose

Answer 1

Elevation of boiling point is a colligative property and it depends upon the no of solute particles

Elevation.of boiling point increase s with the increase in no of solute particles

A)2 b)3 c)1 d)1

Hence the and is b
