Which solute, an electrolyte or a nonelectrolyte, has the greater effect on the boiling point when a given amount of each solute is dissolved in the same mass of water?
a)the nonelectrolyte does because it disperses into molecules.
b)the electrolyte does because it disperses into molecules.
c)the nonelectrolyte does because it dissociates into ions.
d)the electrolyte does because it dissociates into ions.

D)The electrolyte does because it dissociates into ions.

Expalantion: At Boiling point, atmospheric pressure is equal to vapor pressure.

When a solute is added to the pure solvent, it reduces the vapor pressure of solution. And thus more heat is required to generate enough vapor pressure to make it equal to atmospheric pressure.Thus there is an elevation in boiling point.

=Elevation in boiling point

=molal boiling point constant

m=molality

Elevation in boiling point is a colligative property as it depends on the amount of substance i.e molality.

As electrolytes dissociate into ions and non electrolytes do not dissociate, electrolytes lead to addition of more amount of solute. Thus electrolytes have the greater effect on the boiling point when a given amount of each solute is dissolved in the same mass of water.
