|
Solutions are clear in appearance.
|
|
|
Substances in solutions are large enough to be seen.
|
|
|
Solutions exhibit scattering of light or the Tyndall effect.
|
|
|
Substances in solutions can be separated through filtration.

Detailed explanation-1: -A true solution is transparent and clear. Components of the solution are the substances that make up a homogeneous solution. It consists of two main components: a solvent and a solute.
Detailed explanation-2: -The definition of true solution is a homogeneous mixture of two or more substances in which substance dissolved (solute) in solvent has the size of the particle less than 10−9m or 1nm. So the perfect example of true solution is ENO salt in water.
Detailed explanation-3: -They do not scatter a beam of light and hence do not show Tyndall effect. They cannot be filtered from ordinary filter paper. Hence solutions are always clear and transparent. Examples of solutions are: salt in water, sugar in water.
Detailed explanation-4: -A true solution is always clear and transparent.
Detailed explanation-5: -Properties of the true solution The true solution is completely transparent or colourless. The true solution has solute particles that do not dissolve when mixed with water or other liquids. The true solution does not scatter light as the particles are nearly non-existable in size.
