Question

Explain the following with examples .
i) Saturated solution
ii) Colloid
iii) Suspension​

Answer 1

Saturated solution:

The term saturated solution is used in chemistry to define a solution in which no more solute can be dissolved in the solvent (more solute can be dissolved if the solution is heated). Examples of saturated solutions is our daily life are saturated salt solutions, fizzy drinks (saturated with $CO_{2}$).

Colloid:

In chemistry, a colloid is a phase separated mixture in which one substance of microscopically dispersed insoluble or soluble particles is suspended throughout another substance. Typically, colloids do not completely settle or take a long time to settle completely into two separated layers. Colloids can't be separated by normal filteration methods. Examples of colloids include milk, blood, etc.

Suspension:

In chemistry, a suspension is a heterogeneous mixture that contains solid particles sufficiently large for sedimentation. The particles may be visible to the naked eye, usually must be larger than one micrometer, and will eventually settle, although the mixture is only classified as a suspension when and while the particles have not settled out. Examples include a mixture of water and flour, muddy water, etc.

Answer 2

Answer:

(a) Saturated solution:

Solution in which no more solute can be dissolved at a particular temperature is known as saturated solution. ... The solute particles in suspension do not dissolve but remain suspended throughout the medium. For example Paints, Muddy water chalk water mixtures etc.

b. Pure Substance

Pure substances are substances that are made up of only one kind of particles and has a fixed or constant structure. An element is a pure substance as it cannot be broken down or transformed into a new substance even by using some physical or chemical means. Elements are mostly metals, non-metals or metalloids.

c. Colloids

Colloids are defined as a mixture where one of the substances is split into very minute particles which are dispersed throughout a second substance. The minute particles are known as colloidal particles. Colloids are heterogeneous mixtures in which the size of solute particles is intermediate between those in true solutions and those in suspensions and are big enough to scatter light
