Question

#1: A concentration in terms of volume/volume is used to describe which of the following types of solutions?

A. solutions with a solid solvent and a solid solute

B. solutions with a liquid solvent and a liquid solute

C. solutions with a solid solute and a liquid solute

D. solutions with a liquid solvent and a solid solute

**I'm not really sure on this one :( what do you think?

Answer 1

I believe the correct response would be D. Solutions with a liquid solvent and a solid solute. This is primarily for concentrations measured in terms of number of moles/volume.

Answer 2

B.
This method of expressing concentration is employed with solutions where both the solute and solvent are liquid. This is because it is easy to measure the volume of a liquid compared to that of a solid. Usually weight/weight is used in concentrations involving only solids.
