Question

Which of the following solutions will have highest boiling point:
A. 1% solution of glucose in water
B. 1 % solution of sucrose in water
C. 1 % solution of sodium chloride in water.
D. 1 % solution of calcium chloride in water.

Answer 1

Correct Answer - C
Their molar concentration will be
`"Glucose" = 10/180 M, "Sucrose"= 10/342 M`
`NaCI=10/58.5 xx 2M, CaCl_(2) = 10/111 xx 3M`
`=0.34 m = 0.27 M
Thus, concentration of particles in NaCI is highest.
