If the solubility of $H_2S$ in water at $STP$ is $0.195 \, m$,what is the value of $K_H$ in $bar$?

Calculate the solubility of gas in water at $1.2 \text{ atm}$ and $25^{\circ} C$ if Henry's law constant is $0.45 \text{ mol dm}^{-3} \text{ atm}^{-1}$ at $25^{\circ} C$.

Which of the following salt's solubility increases appreciably with an increase in temperature?

Choose the correct statement about Henry's constant $(K_H)$.
$I$. $K_H$ increases with increase in temperature generally.
$II$. $K_H$ decreases with increase in temperature generally.
$III$. $K_H$ is the characteristic constant of the gas-solvent system.

If $CO_2$ gas having a partial pressure of $1.67 \ bar$ is bubbled through $1 \ L$ water at $298 \ K$,the amount of $CO_2$ dissolved in water in $g \ L^{-1}$ is approximately. (Henry's law constant of $CO_2$ is $1.67 \ kbar$ at $298 \ K$)

Give an example of a solution where both the solute and the solvent are in the gaseous state.
