the precipitate. Obtain an Erlenmeyer flask and a Buchner funnel. This will be done by selecting from the Equipment section on the toolbar and selecting Erlenmeyer Flask-250mL. Next‚ right click on the flask and select Buchner Funnel. Right click on the beaker and select Pour/Decant. Move the beaker above the funnel and you will see a white area at the bottom of the flask. 4. Lastly‚ you will need to record the weight of the precipitate. Right click on the flask and select Buchner Funnel.

Placed 7 g of clove buds/ground cloves into the flask and added 150 mL water. Began heating with a Bunsen burner to create a steady rate of distillation. While distilling‚ we continued to add water from the addition funnel‚ as needed‚ to maintain the level of the liquid in the distilling flask. Continued until 75 mL was collected. Chilled.

TWO-BASE EXTRACTION OF BENZOIC ACID‚ 2-NAPHTHOL‚ AND NAPHTHALENE FROM UNKNOWN SAMPLE # 131 Douglas G. Balmer (T.A. Mike Hall) Dr. Dailey Submitted 11 July 2007 Introduction: The purpose of this experiment was to separate a sample of benzoic acid‚ 2- naphthol‚ and naphthalene of unknown proportions using a two-base extraction method. The three components of the mixture will react differently to sodium bicarbonate and sodium hydroxide because each of the bases’ conjugate acids has a different

and filled a 400ml beaker with tap water. Then I got a 125ml Erlenmeyer flask and put in 2.00 grams of Salicylic acid using a scale. For the third step I added 5ml of Acetic Anhydride using a graduated cylinder. Then I added 5 drops of concentrated Sulfuric acid to the Acetic Anhydride and Salicylic acid in the Erlenmeyer flask using a dropper. I then heated the flask in the boiling bath for exactly 10 minutes. I then removed the flask and allowed it to cool on the counter for 4.5 minutes while adding

Abstract: The purpose of this experiment was to determine the percentage purity of the iron(II) salt in an unknown sample. We performed titrations using Potassium permanganate which is a strong oxidizing agent‚ with unknown sample dissolved in deionized water. The result of the experiment was a 99.5% purity for the anhydrous iron (II) ammonium sulfate. Introduction: In this experiment‚ oxidation/reduction (or redox) will be used in the titration analysis of an iron compound. We will use potassium

Purpose 1. To prepare a dry-packed sample of product mixture of ferrocene and Acetylferrocene 2. To separate and purify the components in the product mixture by column chromatography. 3. To check the purity of the components by thin-layer chromatography (TLC). 4. To calculate the yield of acetylferrocene and the percent recovery of unreacted ferrocene.
