Is it the temperature of the solvent minus the temperature of the solution at freezing point?4) For such a phase diagram, a) Do you expect the newly formed bonds (A-B) are stronger than the initial bonds or not? Briefly explain the reason. Is this solution formation reaction endothermic or exothermic? b) Then, is the activity coefficient greater than 1 or not? How would you expect change in volume and change in Enthalpy due to formation of the solution? c) Describe the function (interatomic bond parameter). Explain/compare the bond strength (newly formed A-B vs initial A- A and B-B) depending on sign of the 2-function. T L+α L A Хв B

- Freezing point depression and boiling point elevation can be used to determine the molarmass of proteins. If 5.00 g of a protein is dissolved in 25.00 g of water, Tfp = -7.4 mK(where mK = milliKelvin). What is the molar mass of the protein?What is the strength of the ionic interactions between an ion with 1 positive charges and an ion with 2 negative charges, when the distance between them is 19.4 nanometers and the solvent is water, at 25 oC with a dielectric constant of 78.5?synthetic ion exchange resins. These resins are organic polymeric networks that contain functional groups that are permanently attached to the resin. One such functional group is sulfonic acid, -SO3H. When placed in water, the resin (being a large organic molecule) will not dissolve. However, the ionic functional groups become hydrated and the resin will swell as it takes up waters of hydration. The resin may then be thought of as a solid solution mixture with the functional groups being "dissolved" but the polymer remaining as a solid. The hydronium ion (H3O+) associated with acidic functional groups like sulfonic acid will dissociate just as it would if the acid were free of the resin. If other cations such as Cu2+ or Na+ are added to the resin, an ion-exchange reaction can occur: . Note that one H+ is released for each positive charge bound to the resin. Since the resin exchanges a hydrogen ion for a sodium ion in this reaction, sulfonic acid resins are called cation-exchange…
