• Another word for solution

• A thing that make drinks change colour

• Usually the solid about to be dissolved

If I dissolve sugar in water, what is the solute?

• Water

When a solvent contains as much of the solute as it can hold, the solution is said to be

• supersaturated
• diluted
• saturated
• unsaturated

__________ are made up of solutes and solvents.
