TOPIC 10 : SOLUTIONS

, SOLUTIONS
• A solution is a homogeneous mixture, whose composition and
properties are uniform throughout its entire volume.
• In a solution, the dissolved substance is called a solute, while
the substance doing the dissolving is called a solvent
• The solute is usually present in lesser amounts, while the
solvent is present in greater amount
• E.g., when sugar (a solute) is added to water (the solvent), the
sugar dissolves in the water to form a solution
• When the solvent is water, we refer to the solution as an
aqueous solution (from the latin word aqua, meaning water)
2
, SOLUTIONS
• The dissolution of a solid in a liquid is the most common
method of solution formation
• However, it is also possible to form solutions in gases and solids
• For example;
Air is a homogenous mixture, but it’s also a solution in that
oxygen & other trace gases are dissolved in the gaseous
solvent nitrogen
Alloys, e.g. brass, silver & the gold used to make jewelry,
are also homogenous mixtures of two or more kinds of
metal atoms in the solid state
