Question

a dilute solution of water and milk is prepared. when tested, the solution exhibits the tyndall effect but cannot be separated by filtration. what type of mixture is this?
colloid
solution
suspension

Explanation:

Colloids exhibit the Tyndall effect (scattering of light by dispersed particles) and have particles small enough that they cannot be separated by standard filtration. Solutions do not show the Tyndall effect, while suspensions can be separated by filtration and may settle over time.

Answer:

colloid
