MCQ
The solubility of $CO_2$ in water increases with
- AIncrease in temperature
- BReduction of gas pressure
- CIncrease in gas pressure
- ✓Increase in volume
$\frac {P_1}{P_2}\,=\,\frac {S_1}{S_2}$
$\frac {500}{750}\,=\,\frac {0.01}{S_2}$
$\therefore $ $=\,\frac {750\times 0.01}{500}$ $=\,0.015\,g/L$
