Question

The values of Henry's law constant for $CO_{2}$, vinyl chloride, methane and formaldehyde at 298 K are $1670,611,413$ and $1.8 	imes 10^{-2}$ bar respectively. The solubility of these gases in water at 298 K follows the order

Professor PC Thomas Classes · Answer

Henry's Law: $p=K_{H} \chi \chi=\frac{p}{K_{H}}$ Higher the value of $K_{H}$, the lower is the solubility, $\chi$ under constant P. Gases: $CO_{2}<C_{2} H_{3} Cl<CH_{4}<CH_{2} O$ KH: $1670 \quad 611 \quad 4131.8 	imes 10^{-2}$ bar
