Question 2 • HCISD-Integrated Physics and Chemistry A-CR SUMMER

Which statement best describes a true solution?

Answer
A
A true solution will settle out after a short period of time.
B
A true solution coagulates when heated or boiled.
C
A true solution will not separate in a centrifuge.
D
A true solution has a cloudy appearance.

Explanation

A true solution is a homogeneous mixture with particles small enough that they do not settle out or separate when spun in a centrifuge. Therefore, it will not separate in a centrifuge. Settling and a cloudy appearance are more typical of suspensions or colloids, so C is the best description.
