- 5) The volume of several aqueous copper sulfate (CuSO4) solutions was precisely measured at SATP. All of the solutions were made by adding copper sulfate to 100.00 g of water. ncopper sulfate (mol) Vsolution (mL) 0 100.18 0.0330 100.16 0.0696 100.36 0.111 100.81 0.156 101.62 First, estimate the concentration-dependent partial molar volume of copper sulfate in water by taking finite differences. Second, fit the data to a hyperbola and take a derivative of the hyperbola to accurately calculate the partial molar volume of copper sulfate in water at each concentration. Interpret the partial molar volume at infinite dilution - what must copper sulfate be doing to the nearby water molecules?The vapor pressure of pure THF at 20 °C is 0.1651 atm. When 10 g of an unknown non-volatile non-dissociating solute A is dissolved in 100 g THF, the vapor pressure of solution at 20 °C is 0.1562 atm. Calculate the mole fraction of solute A in the solution. 0.395 а. 0.946 Ob. 0.824 Oc. 0.054 Od. 0.176 е.(c) Are the strengths of the interactions between the particles in the solute and between the particles in the solvent before the solute and solvent are combined greater than, less than, or equal to the strengths of the interactions between solute particles and solvent particles after dissolution? Explain.
- pressure plays an vital role in the solubility of gas in liquid. Solubility is the amount of solute dissolved in solvent. With increasing in the pressure on the liquid system, solubility of gas in liquid increases. As per Henry’s Law, at constant temperature, the mass of a gas dissolved per unit volume of solvent is directly proportional to the pressure of gas in equilibrium. Solute - Solid substanceSolvent - Liquid substance. Solute is mixed into solvent to form solution and solubility is the amount of a substance (solute) mixed in a particular solvent to form solution.When temperature increases -the average kinetic energy of the liquid molecules increases. This increased kinetic energy makes the liquid molecules creating more space between them.With increase in temperature, the intermolecular forces holding the solid particles also decrease. This leads to break them into smaller pieces and makes them readily take space vacant between the liquid particles. This way more solute is…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…A student determines the molar mass of acetone, , She found that the equilibrium temperature of a mixture of ice and water was 1.0C on her thermometer.

- Effect of temperature and pressure on solubility with explationJust because there appears to be a good match between solubility characteristics between solute and solvent doesn’t mean you’ve found a good system. For example, benzyl alcohol appears to have favorable solubility characteristics with fluorenol, but it is a poor choice of solvent. Explain why this might be.Given these values, find the initial mole fraction and initial mass % of the solute (NaCl) Solvent (water) weight: 200g Solute (NaCl) weight: 20.8g Solute (NaCl) Molar mass=58.44 moles of solute (NaCl) = .356
- A polymer of large molar mass is dissolved in the organic solvent dimethylformamide (C3H7NO) at 25 °C, and the resulting solution rises to a final height of 10.8 cm above the level of the pure solvent, as solvent molecules pass through a semipermeable membrane into the solution.
