Hi,
Here is a method of determining alcohol by titration(probably the one you were using?)

Here is a minor variant on the technique:

There are quite a number of methods for determining alcohol in liquids. Here is a brief overview comparison of a few of the more common methods:

Here is a book review that includes ethanol analysis techniques - check the table of contents to link to the right spot. This book might be available on interlibrary loan - see your local library.

If you still want more, I recommend using a search of Chemical Abstracts, which should produce more relevant literature than you can possibly read. I am sorry, but a fairly determined search appears to turn up dichromate oxidation of ethanol as the a fairly universal standard for determination of ethanol in wine by titration. Have you explored this with your teacher?
Good luck on the project!!! And above all else, have fun with it!

). Our current method uses potassium dichromate so if theres another one out there, PLEASE HELP!
