Final answer:
The statement that Haemaccel is an example of a colloid solution is true due to its colloidal properties and the presence of proteins and large molecules that scatter light.
Step-by-step explanation:
An example of a colloid solution would be Haemaccel. The statement is true. Colloids are a type of heterogeneous mixture where the dispersed particles are of intermediate size between those in a solution and those in a suspension. Unlike particles in a solution, colloidal particles do not dissolve but remain evenly distributed throughout the medium, and unlike a suspension, they do not settle out upon standing. The dispersed particles in colloids are large enough to scatter light, known as the Tyndall effect, making the medium appear opaque. Haemaccel, being a plasma expander used in medicine, has colloidal properties because it contains proteins and other large molecules that act as colloids when mixed with plasma.
