In case of a solution (not of a solid in a liquid), whose total volume is less than the sum of the volumes of its components in their pure states, solubility is__________________?
Correct answer: D. Increases with rise in pressure
- A. Independent of temperature
- B. Unchanged with pressure changes
- C. Increased with decrease in pressure
- D. Increases with rise in pressure
Explanation
A negative volume change on mixing means pressure favors the mixed solution, increasing the amount that can dissolve. Therefore solubility increases as pressure rises.
