In your discussion you should make a conclusion and then explain how your experimental results and observations support your conclusion. The points below should help you identify the information you have available from this experiment to support your conclusion. Submit completed lab report by due date. Be sure to include the following:
Purpose. Based upon the introduction in your lab manual, what are you trying to find with your experiment?
Claim. Based upon the purpose of your experiment, what claim can you make using your experimental evidence?
Discussion of your results:
For Experiment 7, you should include:
Balanced chemical reaction.
Information about the reactants and products.
Observations about the reaction that show that a reaction occurred.
The yield for the reaction. Theoretical yield, experimental yield, and % yield.
For Experiment 8, you should include:
Include the Ksp expression for this reaction.
Include the absorption spectrum.
Include the calibration curve.
Explain how your experiment results support your claims.
Explain how your results with the known materials validate your procedure.
Explain discrepancies between expected and experimental results.
Uncertainty and Error in measurements.
Identify possible sources of uncertainty and error in your measurements.
Use evidence from your laboratory notebook to support your error analysis.
Discuss how the direction of each source of error affects the results.
