Which of the following is not true about the dilution of a solution?
The concentration decreases.
The amount of solvent increases.
The amount of solute remains constant.
The volume decreases.
In the dilution of a solution, the solution is added with an additional amount making the concentration of the solute over the solution less than the original. In this case, the number of solute particles remains the same. Answer to this problem is D. The volume decreases.
