Which of these solutes raises the boiling point of water the most?

A) Ionic lithium chloride ($\mathrm{LiCl}$)

B) Ionic sodium chloride ($\mathrm{NaCl}$)

C) Molecular sucrose (C12H22O11CX12​HX22​OX11​)

D) Ionic sodium phosphate (Na3PO4NaX3​POX4​)

E) Ionic magnesium bromide (MgBr2MgBrX2​)

Answer:- B) Ionic sodium chloride ($\mathrm{NaCl}$)

The water molecules require more energy to produce enough pressure to escape the border of the liquid. The more salt (or any solute) added to water, the more you raise the boiling point. Presence of soluble salts surges the boiling point of water since, salt is a non -volatile solute which is responsible for boiling point elevation since sodium chloride dissociates into sodium and chlorine ions .
