Question

what are aerosol, foam, emulsion ,gel, sol and Solid sol.(colloidal solutions)

Answer 1

THANKS TO BOOST UP MY CONFIDENCE

#Aerosol =>> It is a suspension of fine solid particles , liquid droplet in air or another gas.
E.g. = Fog ,Dust ,Forest

#Foam=>> it is a colloidal system.
An intimate mixture of two substances

#Emulsion =>> it is a Dispersion of one liquid into another liquid which is immiscible.

#Gel =>> it is a form of sol, a solution in which the solid particles are meshed such that a rigid or semi fluid mixture result.
E.g. Gel fruit, Jelly ,Jelatin etc.

#Sol =>> A Sol is a colloidal solution suspension of very small solid particles in a continuous liquid medium.
E.g. Blood ,Pigmented Ink etc.

# Solid Sol =>> it is a type of colloid, of the form of one solid dispersed into another continuous solid.
E.g. Pearls ,Green stones etc.

Answer 2

Answer:

Aerosol: When particles of solid or liquid get dispersed in a gaseous medium, the mixture is known as Aerosol. For example – cloud, fog, smoke etc.

• Foam: Foam is a colloidal system where the dispersed phase is gas, and the dispersion medium is solid or liquid. (Solid dispersion medium for solid foam only.)

• Emulsion: Emulsion is a colloidal system where the dispersed phase is liquid, and the dispersion medium is another liquid.

• Sol: Sol is a colloidal system where the dispersed phase is solid, and the dispersion medium is liquid.

• Gel: Gel is a colloidal system where the dispersed phase is solid, and the dispersion medium is liquid.

• Solid sol: Solid sol is a colloidal system where the dispersed phase is solid, and the dispersion medium is another continuous solid.
