Question

A scientist noted the solubility of methane gas in water at 25⁰ C at various pressures. But he entered the wrong pressure values corresponding to the solubility values.

$\begin{matrix} S o l u b i l i t y o f o x y g e n g a s i n w a t e r (m g / L) & P r e s s u r e e x e r t e d o n o x y g e n g a s (i n P a s c a l) 3 & 0.015 5 & 0.006 9 & 0.003 \end{matrix}$

Based on your knowledge about variation of solubility with pressure, help him correct the observation table.

Solution

Increase in pressure increases the solubility of gases. So, as the pressure increases more methane gas is dissolved in water. Therefore the correct table should be:-

$\begin{matrix} S o l u b i l i t y o f o x y g e n g a s i n w a t e r (m g / L) & P r e s s u r e e x e r t e d o n o x y g e n g a s (i n P a s c a l) 3 & 0.003 5 & 0.006 9 & 0.015 \end{matrix}$

A boy was carrying out an experiment on the solubility of a gas in the water.He took a solute gas A and dissolved it in a liquid solvent(Water) B at a particular temperature T and pressure P.At that point he got some solubility value S. Later, he observed the value of solubility by

i)increasing temperature of water from T to T' and

ii)decreasing pressure on water surface from P to P'.

He got the new solubility S'.Then what is the relationship between former solubility S and latter solubility S'?
