Qualitative Analysis of Anions Overview Getting Started Techniques Procedure FAQ Full Lab Manual Introduction & Goals Chemistry & Background Key Questions Prelab Problems Safety Procedure In Your Write-up Experiments Index ChemLab Home		Before Lab Review the section of this manual describing the parts of a lab notebook before you begin. Leave the first few pages of your notebook blank for a table of contents and number subsequent pages. Start your notebook with a brief statement of the objective(s), and a reference for your work. Carefully read the introduction and procedure of the experiment. Complete solutions to the prelab problems. There are six prelab problem's for this week's experiment for you to answer as part of your prelab write up before coming to lab. Remember that these will be turned in before starting the lab. Also prepare an experimental flowchart or outline for Experiment 1. You may write this prelab procedure on the left-hand side of your notebook and use the right hand side for your observationsmade in lab. Since there found throughout this week's procedure for you to answer in your prelab write-up before coming to lab. Also in your prelab, complete an experimental flowchart or outline. You may write this prelab procedure on the left-hand side of the center line in your lab notebook and use the right-hand-side for your observations made in lab. Since there are no calculations for this week's lab, a sample calculation or analysis outline is not required in your prelab for this week. In Lab Be sure to write down exactly what you do in the lab and all your observations, including balanced chemical equations in the "Procedure, Data, and Results" section of your notebook. Before leaving the lab, your TA will check your notebook for completeness and initial it. Uncertainty Analysis An uncertainty analysis evaluates the accuracy of calculated, numerical results. The simplest form of uncertainty analysis is to use the significant figures rules. In this experiment, your results are completely qualitative. You will state which anion your unknown sample contains and support your conclusions with observations. Because nothing is calculated this week, no uncertainty analysis is required. After Lab Be sure that your lab notebook contains sections 1-5 described in the introduction to this manual. Fill out and turn in the data sheets in your manual. In identifying your unknown ion, describe your reasoning in reaching this conclusion and include balanced confirming reactions. Click here to link to page on how to keep a lab notebbok.
