The condition that increases the solubility of the saturated solution needs to be explained. Concept introduction: The solubility of gas is affected by both temperature and pressure. When the temperature is increased, the kinetic energy of the gaseous molecules increases. Due to high kinetic energy, the movement of gas molecules increases and intermolecular bonds between them breaks and they escape from the solution. This results in decrease in the solubility of gas. When pressure is increased, the solubility of the gases increases. According to Henry’s law, the solubility of the gas in liquid is proportional to the pressure of the gas. Thus, solubility of a non-reacting gas increases with increase in pressure and decrease in temperature. There is no change in the solubility of a gas on increasing volume. The increase in volume only increases the rate of the solubility but the amount of solute dissolving in the solvent remains the same.

Experiment: Each team will be provided with 5g of a mixture of acetanilide and salicylic acid. You will divide it into three 1.5 g portions in separate 125 mL Erlenmeyer flasks savıng some for melting point analysis. Dissolve the mixture in each flask in ~60mL of DI water by heating to boiling on a hotplate. Take the flasks off the hotplate once you have a clear solution and let them stand on the bench top for 5 mins and then allow them to cool as described below. Sample A-Let the first sample cool slowly to room temperature by letting it stand on your lab bench, with occasional stirring to promote crystallization. Sample B-Cool the second sample 1n a tap-water bath to 10-15 °C Sample C-Cool the third sample in an ice-bath to 0-2 °C Results: weight after recrystalization and melting point temp. A=0.624g,102-115° B=0.765g, 80-105° C=1.135g, 77-108 What is the percent yield of A,B, and C.
