At a given temperature, Henry's law constant ($KH$) for four gases $ ext{A}$, $ ext{B}$, $ ext{C}$ and $ ext{D}$ in water are $40.3$, $3.3$, $248$, and $1.5$ kbar respectively. Which one of the following gases is most soluble in water?

Question

At a given temperature, Henry's law constant ($KH$) for four gases $	ext{A}$, $	ext{B}$, $	ext{C}$ and $	ext{D}$ in water are $40.3$, $3.3$, $248$, and $1.5$ kbar respectively. Which one of the following gases is most soluble in water?

Accepted Answer

Gas D is most soluble in water. According to Henry's law ($p = KH \cdot x$), solubility is inversely proportional to $KH$. A lower value of $KH$ indicates higher solubility at a given pressure.
