Question

If the K H values for Ar ( g ) , CO 2 ( g ) , HCHO ( g ) and CH 4 ( g ) respectively are 40 . 39 , 1 . 67 , 1 . 83 &#215; 10 - 5 and 0 . 413 , then identify the correct increasing order of their solubilities.

According to the Henry's law, the solubilities is inversely proportional to the hydration constant $K_{H}$ . So, higher the solubility, lower the $K_{H}$ value.

So, the formaldehyde has the lowest $K_{H}$ value. So, it has the highest value of solubility.

The order of solubility is $Ar < {CO}_{2} < {CH}_{4} < HCHO$ .
