Question

Blood is called a colloidal suspension because
A) it has a pH of 7.4.
B) it is alkaline.
C) it consists of the suspended plasma proteins.
D) it consists of the sodium and chloride ions.

Accepted Answer

A colloidal suspension is a mixture in which the solute particles do not settle and are large enough to scatter light. In blood, the suspended plasma proteins are the solute particles that give it a colloidal suspension. The pH and presence of specific ions do not determine a colloidal suspension.
