Correct Answer: Option C
Explanation:
The correct answer is C: Y and Z are deliquescent.
Here's why:
- Deliquescent substances are those that absorb moisture from the air and eventually dissolve in the absorbed water, turning into a solution. In the given scenario, salt Y gained weight, indicating it absorbed moisture from the air. Salt Z, on the other hand, became liquid, which suggests that it absorbed enough moisture to dissolve itself.
This behavior is characteristic of deliquescent salts. So, both salts Y and Z are deliquescent, absorbing moisture from the air and either increasing in mass (Y) or dissolving into a liquid (Z).
