Homework Redox
Please finish the redox titration sheet and work out the half equations and the overall equation for the 'breathaliser test' that I showed you. Suggest reasons why the acidified potassium dichromate test may be inaccurate and research how alcohol is tested for now.
Voltaic Cells
Redox reactions can be used to convert chemical energy to electrical energy. Find out about the first voltaic cell that was made and then look at this video clip to see the basic principles of what happens.
