The Merck Index gives the following data for the solubility of 1 gram of salicylic acid and 1 gram of aspirin: Aspirin (acetylsalicylic acid) 300 mL of H2O 17 ml of chloroform 12 mL of ethyl ether Salicylic acid 460 mL of H20 42 mL of chloroform 3 mL of ethyl ether If 10 grams of aspirin were dissolved in 3000 ml of water, what weight of aspirin would be removed by a single extraction with 3000 ml of ethyl ether? If 10 grams of salicylic acid were dissolved in 4600 ml of water, what weight of salicylic acid would be extracted by two sequential extractions with 2300 ml of chlorofprm for each extraction?

A local company sent you their green alternative for window cleaner to be tested for percent (w/v) acetic acid content. For your experiment, you first standardized your NaOH titrant with 0.8053 g of (99.80 % purity) KHP. You used 40.60 mL of NaOH for your standardization. After that you then analyzed a 50.00 mL sample and found that you needed 33.20 ml NaOH to reach the end point. Summary of results: Standardization Sample analysis KHP Weight (g) Purity NaOH (mL) used Determine the following: 0.8053 g Volume of sample 50.00 mL 99.80% NaOH (mL) used 33.20 mL 40.60 mL a.

20 ml of a 100 mg/l phenol solution in water is placed in a vial with 20 ml of a fluorocarbon solvent. The organic phase (fluorocarbon solvent) is immiscible with water. The vial is completely filled with the two phases, thus there is no air or contaminant volatilization. After an hour of agitation, the two phase system reaches equilibrium. The two phases are separated and the fluorocarbon is analyzed for total phenol. The resulting phenol concentration in the organic phase is 16.0 mg/l. Compute the unitless partition coefficient (KF-W) for phenol. Compare your calculation with KF-W obtained from an empirical relationship: log10KF-W 0.71 - 0.862log10 CWsat. KF-W means the partition between the fluorocarbon solvent, F, and water, W. Only typed solution.
