MCQ
The solubility of a gas in liquid generally increases with :-
- AIncreases in temperature
- BReduction in gaseous pressure
- ✓Decrease in temperature and increase of gaseous pressure
- DAmount of liquid taken
In such case, the total vapour pressure of the solution is the sum of the partial vapour pressures of components of the solution.
