Question 6 • *25-26 KCS18 Chemistry IC

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?

Answer
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.

Explanation

Boiling-point elevation depends on the number of dissolved particles: more particles cause a greater increase in boiling point. An electrolyte dissociates into ions in water, producing more particles than the same amount of a nonelectrolyte, which remains as molecules. Therefore, the electrolyte has the greater effect.
