Question

Which is not a characteristic of true solutions? 1. exists in only a single phase 2. homogeneous 3. passes through a filter 4. settles out?

Answer 1

The answer is no.4 Settles out

- Because the solute particles in the true solution doesn't settle, and it can diffuse rapidly, pass through filter paper.

- But the solute particles in the colloidal solution can be made to settle by centrifugation.

Answer 2

The correct answer is 4. settles out

Step-by-step explanation:

A chemical solution is the homogeneous mixture of one or more substances dissolved in another substance in greater proportion. It is composed of solute and solvent, where the solute is the substance that dissolves and the solvent that dissolves it. In other words, the solvent is the species found in the highest proportion and the solute is the species in a smaller proportion. Different solutions may occur in the solutions in which solids, liquids or gases act as solutes or as solvents.

So, the correct answer is 4. settles out, because the solution resulting from the mixture of the two components will have a single recognizable phase (solid, liquid or gaseous) even though their components have different phases.
