Question

What are emulsions. Give an example

Answer 1

an emulsion is a colloid of two or more immiscible liquids where one liquid contains a dispersion of the other liquids
example: oil and water mixtures are emulsions when shaken together

Answer 2

Answer:

The properties of emulsion are as follows:

(1) The particles of a liquid disperse phase are globules (or droplets) which are larger in size than the size of disperse phase particles in sols.

(2) The globules show Brownian motion and Tyndall effect

(3) The globules are often negatively charged and show electrophoresis.

(4) The globules get coagulated on addition of electrolytes containing divalent or trivalent cations.
