Question

a beam of light passes though a liquid in a test tube without scattering. which type of mixture is most likely in the test tube?
colloid
emulsion
solution
suspension

Explanation:

The Tyndall effect, which is the scattering of light by particles in a mixture, is not observed in solutions as the solute particles are very small. Colloids, emulsions, and suspensions show the Tyndall effect due to larger - sized particles.

Answer:

C. solution
