Question

Is urea a colloid?

Answer 1

Urea is not a colloid, It is a true solution.

Solution: A homogeneous mixture of two or more components having particles smaller than 1 nm is called a solution.

1. examples of solutions are salt in water and sugar in water solutions, soda water, etc.

Colloid: A colloid is a type of assemblage in which one component is broken down into incredibly small particles that are dispersed into a different substance.

1. Colloidal particles are the name of small particles.
2. Colloids are essentially liquids consisting of solute particles ranging in size from 1 nm to 1000 nm.
3. Heterogeneity is a characteristic of colloids.

Hence, urea is a solution.
