(a) The term saturated solution is used in chemistry to define a solution in which no more solvent can be dissolved. It is understood that saturation of the solution has been achieved when any additional substance that is added results in a solid precipitate or is let off as a gas.
Eg: Saltwater
(b) Pure substance: A material that is composed of only one type of particle.
Eg: Gold, oxygen and water.
(c) Colloid: A homogeneous non-crystalline substance consisting of large molecules or ultramicroscopic particles of one substance dispersed through a second substance.
Eg: Gels, sols and emulsions.
(d) Suspension: A suspension is a heterogeneous mixture in which solute-like particles settle out of a solvent-like phase sometime after their introduction. We apply the word suspension when particles are big enough to eventually settle.
(a) Saturated Solution : A solution in which no more solute can be dissolved without raising temperature is called saturated solution. For example, 36g of salt in 100g of water.
(b) Pure substance : The substances that are made up of only one type of particles are called pure substances.
(c) Colloid: A colloid is a heterogeneous mixture whose particles are not as small as solution but they are so small that cannot be seen by naked eye. When a beam of light is passed through a colloid then the path of the light becomes visible. For example milk, smoke etc.
(d) Suspension: A suspension is a heterogeneous mixture in which solids are dispersed in liquids. The solute particles in suspension do not dissolve but remain suspended throughout the medium. For example Paints, Muddy water chalk water mixtures etc.
