What does a solubility curve show?
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'?
