Explanation:
Solubility is physical property of a chemical substance. It is defined as the ability of a given chemical substance, called solute, to dissolve in a given solvent.
Potassium nitrate is an ionic compound, that is moderately soluble in water.
The dissolution potassium nitrate in water is an endothermic process. Thus, the solubility of potassium nitrate increases, as the temperature increases.
The solubility curve of potassium nitrate also shows that the solubility of the potassium nitrate salt increases with temperature.
Therefore, the endothermic dissolution of potassium nitrate explains the solubility curve of potassium nitrate.
The solubility of potassium nitrate in water has been graphed as the endothermic reaction.
The solubility curve has been graphed for the dissolution of potassium nitrate with increase in temperature. The solubility has been defined as the dissolution of the compound with interaction of solute molecules with solvent molecules.
Solubility curve:
The solubility curve has been demonstrating the increase in the solubility of potassium nitrate with increase in heat energy. It has been indicating that the energy has been absorbed by the nitrate molecules for the increase in solubility.
The energy has been absorbed by the molecules in the endothermic reaction. Thus, the solubility of potassium nitrate in water has been graphed as the endothermic reaction.
