Which of the answer choices correctly describes a solution that has less of a solute dissolved in it than the maximum amount possible for a given temperature and pressure?

colloidal solution

saturated solution

supersaturated solution

unsaturated solution
is it d?

yes

thank you

Yes, the correct answer is "unsaturated solution."

To arrive at this answer, let's break down the question and the options:

The question is asking for a solution with less of a solute dissolved in it than the maximum amount possible for a given temperature and pressure. In other words, it's asking for a solution that has not reached its saturation point.

The options are:
a) colloidal solution
b) saturated solution
c) supersaturated solution
d) unsaturated solution

To find the correct choice, we can eliminate the options that don't fit the given condition.

a) A colloidal solution is a type of mixture in which the particles of the solute are suspended evenly throughout the solvent. It doesn't provide any information about the concentration of the solute relative to the saturation point. Thus, we can eliminate this option as it doesn't meet the criteria.

b) A saturated solution is a solution that contains the maximum amount of solute that can be dissolved at a given temperature and pressure. Since the question specifically asks for a solution that has less of a solute dissolved than the maximum amount possible, we can eliminate this option.

c) A supersaturated solution is a solution that contains more solute than is normally possible to dissolve at a given temperature and pressure. This exceeds the saturation point, so it doesn't fit the criteria given in the question. We can eliminate this option.

d) An unsaturated solution is a solution that has less of a solute dissolved in it than the maximum amount possible for a given temperature and pressure. This option correctly describes a solution that has not reached its saturation point. Therefore, "unsaturated solution" is the correct answer.

So, you are correct! The answer is d) unsaturated solution.
