n Experiment 1 we measured the solubility in water of a readily soluble substance at different temperatures and determined four important thermodynamic quantities (ΔH0 = 19.71 ΔG0 = - 4.21 , ΔS0 = 80.22, and K298 = 5.47) for the dissolution process. The same four thermodynamic quantities can be determined for the dissolution of a sparingly soluble substance in water such as benzoic acid, but the numerical values are then quite different and reflect the differentiation between readily and sparingly soluble substances in water. Predict how you expect each of the four thermodynamic quantities for the dissolution of benzoic acid in water will differ from the values you determined for the dissolution process of potassium nitrate. Use for your prediction words like “larger” or “smaller”, “change sign” or “order of magnitude difference” and motivate your prediction in each case.
