Q. If 0.1 M solutions of each electrolyte are taken and if all electrolytes are completely dissociated, then whose boiling point will be highest ?
A) Glucose
B) KCl
C) $BaCl_{2}$
D) $K_{2}\lbrack Fe(CN)_{6}\rbrack$
Explanation
(d)
Elevation in boiling point is a colligative property, i.e., depends upon the number of particles. Hence, the electrolyte which give largest number of particles in the solution, has the highest boiling point.
Since $K_{2}\lbrack Fe(CN)_{6}\rbrack$ gives largest number of particles, i.e., 5, hence it has the highest boiling point.
