Vedclass · Answer

(C) The decrease in vapor pressure $(V.P.)$ is proportional to the van't Hoff factor $(i)$ multiplied by the molar concentration $(C)$.For $0.1 \ M \ KCl$,$i = 2$,so $C 	imes i = 0.1 	imes 2 = 0.2$.For $0.1 \ M$ Urea,$i = 1$,so $C 	imes i = 0.1 	imes 1 = 0.1$.For $0.1 \ M \ BaCl_2$,$i = 3$,so $C 	imes i = 0.1 	imes 3 = 0.3$.For $0.1 \ M \ NaCl$,$i = 2$,so $C 	imes i = 0.1 	imes 2 = 0.2$.Since $0.1 \ M \ BaCl_2$ has the highest value of $C 	imes i$,it causes the maximum decrease in the vapor pressure of water.

Which of the following substances,when dissolved in water,causes the maximum decrease in the vapor pressure of water?
