Q. $K_H$ values for $Ar_(g)$, $CO_{2(g)}$, $HCHO_{(g)}$ and $CH_{4(g)}$ are $40.39$, $1.67$, $1.83 \times 10^{-5}$ and $0.413$ respectively. Arrange these gases in the order of their increasing solubility.

Solutions

Solution:

Higher the value of $K_H$, the lower is the solubility of gas in the liquid.
Thus, the order of increasing solubility is
$\begin{matrix}&Ar&<&CO_{2}&<&CH_{4}&<&HCHO\\ K_{H} \,value&40.39&&1.67&&0.413&&1.83 \times 10^{-5}\end{matrix}$
