- Colloidal solution: It is a heterogenous mixture in which one substance of which particles are insoluble and microscopically suspended throughout the other substance.
- It has two components one is the substance that is suspended in the mixture and is known as the dispersed phase and the other component is the dispersing medium into which the dispersed phase is suspended.
- For example, milk is a colloid in which fats, water, and proteins act as the dispersion phase which is suspended throughout the dispersion medium which is liquid in milk.
Copper sulphate solution: Copper sulphate solution is a homogeneous mixture in which copper sulphate completely dissolves in water. The particle size is microscopically very small, does not remain suspended throughout the solution and is not able to scatter the beam of light.
Milk: Milk is a colloid in which fats, water, and proteins act as the dispersion phase which is suspended throughout the dispersion medium which is liquid in milk.
Smoke: It is a type of colloidal solution which is aerosol. In smoke, the dispersed phase is the dust suspended in the air which is the dispersing medium.
Muddy water: It is not a colloid. In muddy water, mud is added to the water. Mud does not dissolve in water but gets suspended in it. The particle size is also very large which can be seen with the naked eyes.
Butter: Butter is a colloidal solution as it is heterogeneous but seems like homogeneous and particles of the dispersed phase are microscopically tiny and suspended throughout the dispersing medium. There are water molecules trapped in between the fat molecules.
Sugar solution: Sugar solution is not a colloidal solution. It is a true solution in which sugar completely dissolves in water. The particle size of the solution is very small and does not scatter the light beam. Particles of solute(sugar) do not get suspended throughout the solution.
Face cream: It is a colloidal solution. It is an emulsion in which both dispersing phase and dispersing medium are liquids.
Lemonade: It is a true solution in which lemon and sugar completely dissolve in water. The particle size of the solution is very small and does not scatter the light beam. Particles of solute(lemon and sugar) do not get suspended throughout the solution.
Hence, Butter, face cream, smoke, milk are the colloids.
