Question

The solution in which saturation is not achieved is called:

• A. Super saturated
• B. Unsaturated
• C. Saturated
• D. Suspended

Hint:

In unsaturated solutions, more solute can still be added until the solution reaches saturation.

Answer 1

The Correct Option is B

The solution in which saturation is not achieved is called: 

• Option 1: Super saturated - This refers to a solution that holds more solute than it can normally dissolve at a given temperature. It is a state of saturation, but in excess.
• Option 2: Unsaturated - This is the correct answer. An unsaturated solution is one in which the solvent can still dissolve more solute. Saturation has not been achieved yet.
• Option 3: Saturated - A saturated solution is one in which the solvent has dissolved the maximum amount of solute possible at a given temperature and pressure.
• Option 4: Suspended - A suspended solution is one where solid particles are temporarily dispersed in the solvent but have not dissolved.

Explanation:

An unsaturated solution occurs when the solute has not reached the point of saturation, meaning more solute can still dissolve in the solvent. This is the state before reaching a saturated solution.

Answer 2

The question asks what a solution is called when it has not yet reached saturation. Check each option against that specific condition.

1. Super saturated: this describes a solution that has gone past saturation, holding even more solute than the limit allows, the opposite of not yet reaching saturation.
2. Unsaturated: this describes a solution that can still dissolve more solute at the given temperature, meaning it has not yet reached its saturation point. This matches the question exactly.
3. Saturated: this describes a solution that has reached its limit exactly, not one that has fallen short of it.
4. Suspended: this is not a standard classification for how much solute is dissolved; it instead describes particles that have not dissolved at all and remain floating.

A solution that can still take on more solute, having not yet hit its limit, is called unsaturated.

So the correct answer is unsaturated.
