Which of the following statements is /are correct?

(i) Seawater boils at a lower temperature than fresh water.
(ii) $\Delta S$ is higher for the vaporisation of pure solvent than the vaporisation of solvent from a solution containing a non-volatile electrolytic solute.
(iii) The boiling point of water is lower than that of glucose water.

(ii) and (iii)

The correct answer is Option (2) → (ii) and (iii) ##

Sea water has a greater amount of salts as compared to fresh water. The presence of salts decreases the vapour pressure and, hence, the elevated boiling point. Similarly b.p. of glucose water higher than normal water.
