Abeam 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

Solution

Explanation:

In a solution, the particles of the solute are evenly distributed in the solvent, while being in the same phase (unlike colloids, emulsions or suspensions), this allows light to directly pass through the test tube (ie without scattering). So the answer is that the type of mixture is most likely a solution.
