how to calculate the amount of 1,4 dibromobenzene and 4 chloroaniline in a solution before extraction....
50:50 mixture of Naphthalene and 4-Chloroaniline prepared, the extraction occurred using an ether solution. The mixture was prepared by a professional and is both accurate and precise. All glassware was cleaned with acetone. The SDS reports the following MPs: naphthalene = 80-82C and 4-chloroaniline = 67-70C • Mass of mixture: 1.992 g • Recovered Mass of naphthalene: 0.982 g • Mass of 4-chloroaniline: 1.032 • Naphthalene MP: 79.5 - 83.9°C • 4-Chloroaniline MP: 63.5 - 71.9°C Calculate the percent yield...

Experiment: A mixture of equal proportions of benzoic acid, ethyl 4-aminobenzoate, and 1,4-dimethoxybenzene are to be separated by extraction using the solvent diethyl ether. Day 1: Part A. Isolation of the basic component: In a small beaker, dissolve 3 g of the mixture (benzoic acid, ethyl 4-aminobenzoate, and 1,4-dimethoxybenzene) in 30 mL of diethyl ether and transfer the mixture to a 125- mL separatory funnel (see Fig. 1) using a little diethyl ether to complete the transfer. Add 10 mL...

Need help on providing reactions that describe the acid-base
extraction and neutralization processes used in this experiment.
Provide a statement of solubility of each starting material and
product.
The experiment to be performed this week involves liquid-liquid extraction using a separatory funnel. Read chapter 15 in Zubrick to familiarize yourself with the use of the glassware for extraction and washing. Acid/Base Extraction Liquid-liquid extraction is a technique that can be used to physically separate two substances that have varying solubility...
