Question 5 • HCISD-Integrated Physics and Chemistry A-CR SUMMER

Which is a characteristic of a homogeneous mixture that is a liquid?

Answer
A
It exhibits the Tyndall effect.
B
Brownian motion is not visible in it.
C
It cannot be separated using filtration.
D
It has at least two phases.

Explanation

A homogeneous liquid mixture is a solution: its components are evenly distributed in a single phase. The dissolved particles are too small to be caught by ordinary filtration, so it cannot be separated using filtration. The Tyndall effect and visible Brownian motion are characteristics associated with colloids, which are heterogeneous mixtures.
