Question

When salt dissolves completely in water, which term best describes the role of water in the salt-water mixture?

molarity
solute
solvent
concentration

Answer 1

In the salt-water mixture, water acts as the **solvent**. The solute in this case is the salt (sodium chloride). The solvent is the substance that dissolves the solute, while molarity and concentration refer to the amount of solute per unit volume of solution.
