Question

What is true about the dilution of a solution? A. The amount of solute decreases. B. The volume remains the same. C. The amount of solvent increases. D. The concentration increases.

Answer 1

During dilution, additional amount of solvent is added to the solution which decreases the concentration of the solution. However upon the addition, the solvent amount remains the same not the concentration. Therefore the answer to thsi problem is C>

Answer 2

The answer is the amount of solvent increases. In a dilution all you do is add solvent to a solution which causes the concentration of a given amount of solute to go down therefore diluting the solution.

I hope this helps. Let me know if anything is unclear.
