Question

1. Explain how heat effects the solubility of gas in a solvent. How is different from how heat effects the solubility of a solid solute in a solvent? (5 pts) 2. How does pressure effect the solubility of gas in solvent? (5 pts) 3. 9g of a nonelectrolyte solute was dissolved in enough water to produce a 500.0 ml solution. The osmotic pressure was measured to be 1871.1 torr at 300.0K. What is the molar mass of the solute? (5 pts) 4. If you make a 0.800 m aqueous solution of glucose (sugar), what would be its boiling point and freezing point (K.-0.51 Cin, Kf = 1.86 C/m). (5 pts) 18 : looC+0.yoSC:loo.1nc

Explanation / Answer

1. Solubility of gas in a solvent decrease on giving heat while solubility of solid increase on giving heat. Because on giving heat gas particles gain more kinetic energy so they tend escape outside solution due to motion so solubility decrease while when we give heat to solids, they use it in breaking their own attractions so they become more soluble on giving heat.
