Read the description for this virtual lab and perform the experiment described
In your lab report include a brief description of the procedure and include the reactions used
Perform the titration at least three times to get an average number, standard deviation and 90% confidence interval
Check your answer against the computer
In your discussion explain why your results may differ from the actual value
Exploring Oxidation-Reduction Reactions Design an experiment to order Cu, Mg, Zn and Pb from strongest to weakest reducing agent
http://chemcollective.org/vlab/106
Read the problem description and design experiments to measure the relative oxidation potential of the metals
Record your observation and present them in your lab report
Outline your logic in ordering the metals
In your discussion, answer the questions presented in the problem description
EMF measurement
http://amrita.vlab.co.in/index.php?sub=2&brch=190&sim=361&cnt=4
Read the theory and complete the self-evaluation
Perform the EMF measurement laboratory according to the procedure
Select three cathode-anode pairs on which to perform the experiment
In your laboratory report, record the data indicated in the procedure
In your laboratory report, show all the calculations that you used to get the results
In your discussion, provide solutions to the assignment questions
Assignment Expectations
You will complete each of the activities above, and submit a lab report for each summarizing your objectives, procedure, and results. Submit all labs as Word documents or pdf files into your Case drop box.
