Question
Chapter 6, Problem 50P
Interpretation Introduction
Interpretation: The reason for colloids to be essential to life needs to be explained.
Concept Introduction:
Colloids are defined as mixtures containing a substance (insoluble particles) is suspended throughout the other. A colloid is known to be a heterogenous mixture with particle size between the solution and a suspension. These dispersed particles are evenly spread in the dispersion medium. This dispersion medium can be a solid, liquid or gas.
