To avoid bends sickness,the tanks used by scuba divers are filled with air and diluted with ......

In which of the following salts,the solubility increases appreciably with an increase in temperature?

Given below are two statements:
Statement $I$: The Henry's law constant $K_{H}$ is constant with respect to variations in solution's concentration over the range for which the solution is ideally dilute.
Statement $II$: $K_{H}$ does not differ for the same solute in different solvents.
In the light of the above statements,choose the correct answer from the options.

The correct solubility order of $AgF$,$AgCl$,$AgBr$,and $AgI$ in water is:

What is the solubility of a gas in water at $25^{\circ} C$ if the partial pressure is $0.18 \ atm$? $(K_{H} = 0.16 \ mol \ dm^{-3} \ atm^{-1})$

$A$ gas '$X$' is dissolved in water at $2 \ bar$ pressure. Its mole fraction is $0.02$ in solution. The mole fraction of water when the pressure of gas is doubled at the same temperature is
