Chapter 12, Problem 12.3KSP

Interpretation Introduction

Interpretation:

The following elements have to be arranged in order of decreasing solubility in water - $Kr,O_2,N_2$ and the correct answer has to be chosen from following options –

$\begin{array}{l}(a)Kr\approx O_2>N_2\\ (b)Kr>O_2\approx N_2\\ (c)Kr\approx N_2>O_2\\ (d)Kr>N_2>O_2\\ (e)Kr\approx N_2\approx O_2\end{array}$

Concept Introduction:

Solubility of a substance depends on various factors like – chemical structure of the substance, temperature, pH etc,.

Like dissolves like is a Universal rule which states that polar compounds dissolve more in polar solvents and non-polar compounds dissolve more in non-polar compounds.

Dipole moment is the measure of polarity in polar covalent compounds.

Henry's law is a gas law concerned with the solubility of gases in liquid. It states that “the amount of dissolved gas is proportional to its partial pressure in the gas phase.”
