Assertion (A): A solution containing less solute than the saturation level is called an unsaturated solution.
Reason (R): An unsaturated solution can dissolve more solute until it reaches the saturation point.
  • a)
    Both (A) and (R) are true, and (R) is the correct explanation of (A).
  • b)
    Both (A) and (R) are true, but (R) is not the correct explanation of (A).
  • c)
    (A) is true, but (R) is false.
  • d)
    (A) is false, but (R) is true.
Correct answer is option 'A'. Can you explain this answer?

Correct Answer:
A: Both (A) and (R) are true, and (R) is the correct explanation of (A).
Explanation:
An unsaturated solution contains less solute than it can hold at a given temperature, meaning it can still dissolve more solute. The reason explains why such solutions are termed unsaturated.

Understanding Unsaturated Solutions
An unsaturated solution is a fundamental concept in chemistry, particularly in the study of solutions and solubility. Let's break down the assertion and reason:
Assertion (A): Unsaturated Solutions
- A solution that contains less solute than the maximum amount it can hold at a given temperature is indeed termed an unsaturated solution.
- This means that not all the solvent's capacity to dissolve solute has been utilized.
Reason (R): Solubility and Saturation
- An unsaturated solution has not yet reached its saturation point, which indicates that it can still dissolve additional solute.
- This characteristic is crucial because it allows for the potential of solute addition until the solution becomes saturated.
Correct Relationship Between (A) and (R)
- Both the assertion (A) and the reason (R) are true.
- The reason (R) provides a correct explanation for the assertion (A), as it describes why an unsaturated solution retains the ability to dissolve more solute.
Conclusion
- Since both statements are accurate and (R) logically explains (A), the correct answer is option 'A':
- Both (A) and (R) are true, and (R) is the correct explanation of (A).
Understanding this relationship helps in grasping the concepts of solutions, solubility, and the behavior of solutes in solvents, which are essential topics in chemistry.
