The appearance of the system when water is placed in a thick- walled glass tube whose internal volume is 50 c m 3 has to be identified. Concept Introduction: Vapor pressure is nothing but the pressure of a vapor in contact with its liquid or solid form. When a liquid and vapor are in equilibrium the pressure exerted by the vapor is called the equilibrium vapor pressure. If intermolecular force is small the vapor pressure of the substance is high and the boiling point will be low.

Question

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.
