Which of the following ionic solids exhibits a decrease in its solubility in water with an increase in temperature?

Which is the correct order for the solubility of the following compounds in $n$-octane (at identical conditions)? $I$) Cyclohexane $II$) $KCl$ $III$) $CH_3OH$ $IV$) $CH_3CN$

The solubility of a gas in a liquid is directly proportional to the partial pressure of the gas. This statement is known as ...

Given the solubility curves of $KNO_3$ and $KCl$,which of the following statements is not true?

$A$ company dissolves '$X$' amount of $CO_{2}$ at $298 \ K$ in $1 \ L$ of water to prepare soda water. $X = ........ \ \times 10^{-3} \ g$ (nearest integer).
(Given: partial pressure of $CO_{2}$ at $298 \ K = 0.835 \ bar$.
Henry's law constant for $CO_{2}$ at $298 \ K = 1.67 \ kbar$.
Atomic mass of $H$,$C$ and $O$ is $1$,$12$ and $16 \ g \ mol^{-1}$,respectively.)

Calculate the solubility of a gas having partial pressure $0.15 \ bar$ at $25^{\circ} C$.
$[K_{H} = 0.16 \ mol \ dm^{-3} \ bar^{-1}]$
