Question

Quizplus · Accepted Answer

A true colloidal particle will not settle out of the dispersing membrane due to the Brownian motion that keeps the particles in suspension. Colloids can be heterogeneous or homogeneous, and some colloidal particles are too large to pass through a semipermeable membrane. Electrolytes can be used to destabilize colloids, not act as protective colloids. Dispersion is one of the methods of preparing colloids, but not the only method.
