What is a solution? Explain what is meant by 'a solution is clear, but not always colourless'.

A solution is a type of mixture that cannot be separated
easily, such as by hand, with magnets, or with common tools. A solution contains a
solute and a solvent. The solute is the substance in the mixture that will dissolve,
which means that the particles become too small to be seen. A solvent is a liquid, most
commonly water(the universal solvent). The solvent is the substance that actually does
the dissolving. Properties of a solution may change, but some may remain the same. For
example, the water may become sweet when you add sugar, but the water will remain a
liquid. The statement " a solution is always clear, but not always colorless" means that
the solution will be uniform, or the same throughout, but may change color as a result
of dissolving.
