Question

N2 and O2 gases have KH values 76.48 kbar and 34.86 kbar respectively at 293 K temperature. Which one of these will have more solubility in water?

Answer 1

Greater the value of KH, lower is the solubility of gas at same partial pressure. So N2 has KH values of 76.48 kbar and O2 has 34.86 kbar respectively.

As N2 has greater KH value, so it's less soluable than O2. So O2 is more soluable than N2.
