A mixture in which very small particles of one substance are distributed evenly throughout another substance . The particles are generally larger than those in a solution, and smaller than those in a suspension. Paints, milk, and fog are colloids.
How do you describe a colloid?
Colloids are mixtures in which one or more substances are dispersed as relatively large solid particles or liquid droplets throughout a solid, liquid, or gaseous medium. The particles of a colloid remain dispersed and do not settle due to gravity, and they are often electrically charged.
What is a colloid with example?
Examples of Colloids Chemistry
The example for colloidal solution can be given as smog, fog, and sprays. For these colloid examples, the dispersed phase is liquid and a dispersion medium of gas. Usually, these are termed as a liquid aerosol. Examples of colloid chemistry are dust and smoke in the air .
What is a colloid give two example?
A colloid is a kind of solution in which the size of solute particles is intermediate between those in true solutions and those in suspensions. Two ex of colloids are soap solution,starch solution etc .
What are the 3 properties of colloid?
- Properties of colloids are:
- (i) They are heterogenous mixtures.
- (ii) The size of particles of colloids is too small to be seen by naked eye.
- (iii) They scatter light passing through them making its path visible.
What are the types of colloids?
- Sol is a colloidal suspension with solid particles in a liquid.
- Emulsion is between two liquids.
- Foam is formed when many gas particles are trapped in a liquid or solid.
- Aerosol contains small particles of liquid or solid dispersed in a gas.
What type of colloid is toothpaste?
Explanation: Mud and toothpaste are example of sol in which dispersed phase is solid and dispersion medium it s liquid.

Which substance is an example of a colloid milk?
An example of a colloid is milk. Milk is a mixture of liquid butterfat globules dispersed and suspended in water . Colloids are generally considered heterogeneous mixtures, but have some qualities of homogeneous mixtures as well. Smoke is a mixture of particles that are suspended in the air.
What is pure colloid?
(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.
