4-bromobenzoic acid (1.0 g) is dissolved in 20 ml dichloromethane. After addition to a separatory funnel, the dichloromethane solution is treated with 20 ml 3.0 M NaOH solution. After the layers are separated, which layer(s) will contain an organic compound (non-solvent)? What would happen if the aqueous layer is treated with 20 ml 3.0 M HCl?

Expert Solution

The compound will be in Aqueous layer

Draw a picture of a separatory funnel with an aqueous layer and a dichloromethane layer. label each layer. which of the two layers would contain eugenol? Why is the drying agent added to the dichloromethane layer after extraction? why is steam distillation used to isolate the eugenol from the cloves?

If 5.2 g of butanoic acid, C4H8O2, is dissolved in enough water to make 1.0 L of solution, what is the resulting pH? Assuming complete dissociation, what is the pH of a 4.41 mg/L Ba(OH)2 solution? The Kb for an amine is 9.747 × 10-5. What percentage of the amine is protonated if the pH of a solution of the amine is 9.825? (Assume that all OH– came from the reaction of B with H2O.)

A 0.1276 g sample of an unknown monoprotic acid was dissolved in 25.0 mL of water and titrated with 0.0633 M NaOH solution. The volume of base required to bring the solution to the equivalence point was 18.4 mL. (a) Calculate the molar mass of the acid. (b) After 10.0 mL of base had been added during the titration, the pH was determined to be 5.87. What is the Ka of the unknown acid? (10 points)

A CHEM 2242 student dissolved 69.322 g of an unknown monoprotic acid in a 250 mL volumetric flask. The student then transferred 5.00 mL of this solution into a conical flask and diluted the 5.00 mL with another 85.00 mL of DI H2O. Using the second derivative method the student estimated that equivalence occured when 36.86 mL of 0.1066 M NaOH titrant had been added. What is the molarity of the unknown acid solution?

I have an unknown mixture of Benzoic acid, Dimethyl Terephthalate, and Naphthalene dissolved in Dichloromethane. I need to separate the mixture to find the composition using some sort of acid base reation and a distillation. How would I do that? I think that I could use steam distillation to remove the naphthalne but im not really sure on that. Any help would be apprectiated. I start with 25mL of the unknown mixture.
