Q.

The Henry’s law constant (KH) values of the gases (A, B, C) in water are 145, 2×10-5 and 35 kbar, respectively. The solubility of these gases in water follow the order     [2024]

1 B > A > C  
2 B > C > A  
3 A > C > B  
4 A > B > C  

Ans.

According to Henry’s law, higher the value of KH at a given pressure, lower is the solubility of the gas in the liquid. Thus, solubility order of given gases will be: B > C > A
