Question: 1) Write balanced equations for all chemical reactions that should occur in the extraction procedure you are to perform. 2) Devise a flow chart for purification that summarizes the separations to be performed in this experiment. An example of a flowchart can be found in the handout.
PROCEDURE Part 1 Extraction 1. Obtain and wear goggles. Protect your arms and hands by wearing a long-sleeve lab coat and gloves. Conduct this reaction in a fume hood. 2. Weigh out approximately 1.0 g of the sample mixture. Record the mass to the nearest 0.001 g. Transfer the mixture to a 100 mL beaker and dissolve it in 15 mL of diethyl ether.
The following reactions take place in the furnace : (1) Combustion zone: At the base, coke burns to produce CO2, which starts rising upward during the reaction. The reaction is exothermic and heat produced raises the temperature to about 2200 K. This region is called combustion zone. C + O2 ——> CO2 ΔH = -393.4 KJ

Following flow chart shows various methods applied to extract metals at different levels of reactivity. Steps of Extraction of Metals Different methods of extraction are shown in this flow chart. You can see, that metals of high reactivity, electrolysis of molten ore is done to obtain pure metal.
Today, the manufacturing of steel is done by using one of these two methods : Blast furnace: The blast furnace process, also known as the basic oxygen process (BOP), combines raw iron ore with small amounts of steel scrap metal into a furnace. Then, pure oxygen is blown into the furnace, raising its temperature.
The flow chart on the next page outlines a general procedure for separating acidic, basic and neutral organic compounds using the principles of the solubility switch. You will separate a mixture that contains benzoic acid, 4-chloroaniline and naphthalene. C OH O NH2 Cl Benzoic acid mp 122-123° 4-Chloroaniline mp 68-71° Naphthalene mp 80-82°

To recover the maximum amount of the substance from aqueous solution, the extraction is made in two or more successive operations using small portions of the solvent provided. This is called multiple extraction or multi-step extraction. In such a process the aqueous solution is first extracted with a portion of the solvent in a separatory funnel.
