Question 3 • *26-27 CFISD TX-Chemistry A CR

Which is true about dissolving a polar substance in water?

Answer
T
The solvent particles are all nonpolar molecules.
T
The solute particles are carried into the solution.
T
The solute particles have no attraction for the solvent molecules.
T
The solute particles are very different from the solvent molecules.

Explanation

When a polar substance dissolves in water, attractions between the polar solute particles and water molecules help separate and surround the solute particles. The water molecules carry those particles throughout the solution, so choice B, “The solute particles are carried into the solution,” is true. The particles do have attraction to water, rather than none as choice C claims.
