Given is a graph that connects the solubility and the temperature of certain salts. Examine the graph and find out the following: Which substance shows the maximum increase in solubility as temperature increases?

The substance that shows the maximum increase in solubility as temperature increases is Potassium nitrate. The amount of solute in gram required to convert 100 g of a solvent into a saturated solution at a given temperature is known as the solubility of the solute in that solvent. The nature of the solute and the temperature are two factors that influence solubility. The solubility increases with an increase in temperature and decreases with a decrease in temperature.

Given is a graph that connects the solubility and the temperature of certain salts. Examine the graph and find out the following: Prepare a note on the influence of temperature on the solubility of substances. Give examples.

The nature of the solute and the temperature are two factors that influence the solubility of substances. On increasing temperature, the intermolecular space between the molecules of substance increases, this increases their solubility. The increase in kinetic energy due to higher temperature allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions. But, the solubility of gases decreases as temperature increases. For example, the influence of temperature on the solubility of substances can be observed when we dissolve salt in water. We find that more salts can be dissolved in hot water than cold water of same volume.
