Chemistry - Soluble mixtures

Soluble mixtures

Often it is very difficult to decide if something is a mixture or if it is
a pure substance. This is particularly hard with solutions. As we discussed
previously water is a pure substance, but if we dissolve [1] salt in water,
for example, do we have a pure substance or a mixture?

When a solid is dissolved in a liquid, the resulting liquid is called a
solution. [2] It is clear or transparent.

The liquid in which the substance was dissolved is called the solvent. [3]


The substance dissolved is called the solute. [4]

How do we decide if we have a mixture or a pure substance? The rule is
still the same: if the mixture has not reacted to form a new substance then
it remains a mixture.
