Which of the following is NOT true for solutes and solvents?

A. At least one solvent must be dissolved in a solute to make a solution.
B. Solute concentration can be measured in terms of solute moles / solution volume or solute moles / solvent mass.
C. A solvent is the chemical present in a larger amount in a solution.
D. A solute is the chemical present in a smaller amount in a solution.
E. All of these are true.

Thank you!

  1. I think A is the statement that is not true. But if A is not true, then E must be false also.

  5. solvent must be dissolved in a solute
    I would say that it would have to be at least one solute must be dissolved in a solvent not the other way around.

  6. I would make a note to question the teacher about the answers. Because, if A is true then E MUST be fasle, also, since not all of the statements are true. Therefore, the correct answers are A and E.
    A. Solute must be dissolved in solvent.
    B.Concn can be measured in solute mols/volume of solution (molarity) or solute mols/mass solution (malality).
    C. We generally call the one in larger amount the solvent.
    D. We generally call the one in smaller amount the solute.
