I am investigating the titration of 1,2 di-aminoethane with copper(II) sulfate. However, I can't find out what indicator to use or what pH to run the experiment at. Any ideas?

I haven’t heard of this reaction being used in a titration. The conventional procedure uses the derivative of 1,2-diaminoethane, usually referred to as edta. The indicator in this case is murexide at pH 8, which, I suppose, is worth a try.
Incidentally, the complex involves only two of the bidentate ligands to each copper ion, not the expected three!
Risk assessment
Before attempting any practical work based on the advice and suggestions on this website, you must do the following. Identify any hazards, assess the risks from these hazards, and then decide appropriate control measures to reduce the risks. You must have these approved by those in authority in your school or college laboratory. Do not rely on what is said on this website.
For further guidance see our tutorial on Risk Assessment.
