Vedclass · Answer

(C) The elevation in boiling point is a colligative property,which depends on the van't Hoff factor $(i)$ and the molar concentration $(M)$. The formula is $\Delta T_{b} = i 	imes K_{b} 	imes m$. $1.$ $0.01 \ M$ urea: $i = 1$,effective concentration = $0.01 	imes 1 = 0.01 \ M$. $2.$ $0.01 \ M \ KNO_{3}$: $i = 2$ $(K^{+} + NO_{3}^{-})$,effective concentration = $0.01 	imes 2 = 0.02 \ M$. $3.$ $0.01 \ M \ Na_{2}SO_{4}$: $i = 3$ $(2Na^{+} + SO_{4}^{2-})$,effective concentration = $0.01 	imes 3 = 0.03 \ M$. $4.$ $0.015 \ M \ C_{6}H_{12}O_{6}$: $i = 1$,effective concentration = $0.015 	imes 1 = 0.015 \ M$. Since $0.01 \ M \ Na_{2}SO_{4}$ has the highest effective concentration of particles,it will exhibit the highest boiling point.

Which of the following aqueous solutions will exhibit the highest boiling point?
