In Part A of the experiment (Week 1), you will use solubility tests to characterize your unknown compound. 1. To start off, we were provided with aprons and lab safety glasses. Test for cations in aqueous solutions experiment. A systematic, organized approach to this experiment will yield much more meaningful results than a random combination of all 20 bottles of chemicals two at a time! Experiment 6: Analysis of Unknown Solutions Southern California University of Health Sciences Chem 211 Dr. Okezie Aruoma September 19, 2018 Abstract Analysis of unknown solutions is done by developing logical tests to observe chemical reactions to make a qualitative analysis. Since the unknown could be an acid or a base, make sure to handle all spills with care. Physical evaluation. You will then apply what you have learned by characterizing unknown organic compounds in terms of their functional group and solubility behavior. Write a series of tests that you can perform to help you narrow down the identity of the solution. You may find that you cannot identify all the solutions and it may be Procedure: Your goal is to identify an unknown using the skills you have learned so far this unit. In doing this, we found the unknown concentrations of the latter solutions. Aim: To test for metal cations in aqueous solution. Lab Aids #84- Identification of Chemical Reactions Our goal of this experiment was to identify the unknown solution. In this lab we performed different procedures in order to This experiment used dialysis tubing to perform osmosis between a prepared solution of known concentration and two given solutions of unknown concentration. Data: By comparing the solubility of your unknown in several aqueous solutions (described below), you will be able to limit the possible functional groups on your compound. But due to many chemical experiments and space explorations, many new compounds emerge which need to be identified. Identifying Unknown Compounds. 3. Compounds can be identified by two examinations like. Both are used as a safety precaution. Using the data (experimental observations) you have generated, correctly identify the ten unknown solutions. 2. Even if you find one, you can follow few steps mentioned below in identifying the unknown compound. A flow chart, Figure 2, will help guide you in this effort. In this experiment you will carry out several qualitative tests that will allow you to identify functional groups in organic molecules. Wear gloves, goggles and aprons at all times. Chemical evaluation Materials: 1 mol dm-3 solutions of aluminium nitrate, ammonium chloride, ... the knowledge you have- learnt about the reactions of anions and cations to help you plan and carry out experiments to identify the anions and cations in an unknown salt.
