ESSAY

36. A solution is a mixture that has a uniform composition. The composition of a heterogeneous mixture is not uniform throughout. All solutions are mixtures, but not all mixtures are solutions. Salt water is a solution; sand in water is a heterogeneous mixture.

The three common states or phases of matter are: gas, liquid, and solid.

One example would be a solution of salt in water. Another example would be a mixture of iron and sulfur.

The salt and water can be separated by distillation. The iron and sulfur can be separated by using a magnet to attract the iron.
