Question

Gelly is a colloidal solution of:
A. Solid in liquid
B. Liquid in solid
C. Liquid in liquid
D. Solid in solid

Answer 1

Hint: Solution can be defined as that which is made up from two components known as solute and solvent where solute is the substance which gets dissolved and solvent is the substance in which solute is dissolved and both together make solution.

Complete answer:
Colloidal solutions or colloidal suspensions are nothing much but just a mixture in which the substances are regularly suspended in a fluid. A colloid is a very tiny and small material that is spread out uniformly through another substance.
Gelly is substance which is said to semi solid in nature i.e. liquid which has a very little tendency to flow and it is said to be colloidal solution of liquid in solid that why it is said to be semi solid as it contains fluid inside its layer so we can say that it colloidal solution of liquid in solid and this is said to be colloid because it has small insoluble particles that are dispersed in a medium but do not settle out in any particular period of time.

Thus we can say that option B is the correct answer.

Note: Colloids are very much stable in nature. The particles of the dispersed phase are in a state of continuous motion and remain suspended in the solution. Colloids consist of two phases named as the dispersed phase and dispersion medium so they can be known as heterogeneous in nature.
