Interpretation:
The category of the dissolution of ionic solutes is be chosen when this process causes decrease in the entropy and occurs spontaneously.
Concept introduction:
Entropy is defined as the degree of randomness in the system.
An endothermic process is defined as the process in which the energy of the system increases.
Endothermic process is the process that requires or absorbs heat from the surroundings.
In an endothermic process, potential energy of the system increases resulting in increase in entropy of the system.
An exothermic process is the process where the system releases energy.
In an exothermic process, potential energy of the system decreases resulting in decrease in entropy of the system.

- A solution is made by dissolving 34.0 g of NaCl in 100 g of H2O at 0C. Based on the data in Table 8-1, should this solution be characterized as a. saturated or unsaturated b. dilute or concentratedarrow_forwardThe vapor pressures of several solutions of water-propanol (CH3CH2CH2OH) were determined at various compositions, with the following data collected at 45C: H2O Vapor pressure(torr) 0 74.0 0.15 77.3 0.37 80.2 0.54 81.6 0.69 80.6 0.83 78.2 1.00 71.9 a. Are solutions of water and propanol ideal? Explain. b. Predict the sign of Hsoln for water-propanol solutions. c. Are the interactive forces between propanol and water molecules weaker than, stronger than, or equal to the interactive forces between the pure substances? Explain. d. Which of the solutions in the data would have the lowest normal boiling point?arrow_forwardA patient has a “cholesterol count” of 214. Like manyblood-chemistry measurements,this result is measured inunits of milligrams per deciliter (mgdL1). Determine the molar concentration of cholesterol inthis patient’s blood, taking the molar mass of cholesterolto be 386.64gmol1. Estimate the molality of cholesterol in the patient’sblood. If 214 is a typical cholesterol reading among men inthe United States, determine the volume of such bloodrequired to furnish 8.10 g of cholesterol.arrow_forward
