Step 1 of 3

- Sugar is the solute. It is what dissolves.
- Together they make a solution.
The rule
Uniform means the same all through.
A solution is a uniform mixture. When a solid dissolves in a liquid, the solid is the solute. The liquid is the solvent. With two liquids, the smaller amount is the solute.
| Mixture | Solute | Solvent |
|---|---|---|
| Salt in water | Salt | Water |
| Thick sugar syrup | Sugar | Water |
| A little glycerine in a lot of water | Glycerine | Water |
| A little water in a lot of glycerine | Water | Glycerine |
