If you started with 4.6 of 50/50 (by weight) mixture of nitroaniline and benzoic acid what...
You weight out exactly 1.00 mg of benzoic acid and dissolve it in a mixture of 2.0 mL of diethyl ether and 2.0 mL of water. After mixing and allowing the layers to separate, the ether layer is removed, dried, and concentrated to yield 0.68 mg of benzoic acid. What is the Kp value (ether/water) for this system?
1) if you are given a mixture of benzoic acid and white sand with some colored dyes. Write a short procedure to recover pure benzoic acid through recrystallization.
8. In the Separation Project we started with a mixture of benzoic acid, benzhydrol, and anisole dissolved in diethyl ether он OCH3 он In a mixture of diethyl ether and 5% NaOH, which compound(s) would be in the ether layer, and which would be in the aqueous layer? Ether layer: Aqueous layer: If we separate the 5% NaOH layer, put it in a flask with 20 mL ether, and add 5% HCI till the pH reads 5, what is in...
Lab C:
mass %? mole ratio of each of three components: benzoic
acid,dimethyl terephthalate, 4-nitroaniline. (1:1:1 ratio in
compound)
Analysis 1. Determine mass % and mole ratio of each of the three components in the original mixture 2. Conduct melting point analysis of your three components and determine whether you did a good job (or not!) of separating them. 3. Based on how much of each component you mixed, determine product recovery (%).
At what pH would an aqueous solution of benzoic acid be present as 99% conjugate base (benzoate)? (Hint: you will need to know the pKa of benzoic acid)? At what pH would an aqueous solution of m-nitroaniline be present as 99% conjugate acid (m-nitroanilinium, the protonated form)?
17. Draw a flow sheet to show how you would separate a mixture of benzoic acid, 2-naphthol, aniline, and naphthalene. (indicate the solvent, location and composition of each layer). Draw all balanced equations. (6') Reagents available: 3M hydrochloric acid solution, 3M sodium hydroxide solution, 3M sodium bicarbonate solution, saturated sodium chloride solution Solvent available: water, dichloromethane, ethanol, and diethyl ether.

Please answer question 14
13. (1 pt.) Assuming that you started with exactly 0.065g of benzoic acid in your recrystallization, how many moles of benzoic acid did you start with? Show all equations and include all units! 14. (1 pt.) Assuming that you started with exactly 0.065g of benzoic acid in your recrystallization, how many molecules of benzoic acid did you start with? You need to know that Avogadro's number is 6.022 x 10°. Show all equations and include all...
Please show the isolation mechanism (as structures) of a biphenyl and benzoic acid mixture by extraction and use of NaOH and HCl.
An unknown mixture (dissolved in diethyl ether) contains only 2 of the following : benzoic acid, phenol, aniline and napthalene. You use the acid-base extraction method and want to identify the 2 compounds in your original mixture. 1) To separate the organic acid you add NaOH and to separate the organic base you add HCl.In both cases these extractions are followed by extractions with water. Why do we add water? Why is this step important? (A clear explanation please). 2)When...
why isnt the benzoic acid answer?꙼̈
melting points of Benzoic acid and Phenyl succinate are both
121 celsius in the chart. can you please explain?꙼̈
1. An unknown compound X is one of the four compounds listed in the following table. A mixture of X with benzoic acid melts at 89°C, a mixture of X with phenylsuccinate melts at 20°C, and a mixture of X with m-aminophenol melts at 102°C. What is the identity of X? Explain Chemnical mp. ("C)...
