For my Analytical lab, we're trying to figure out a method to determine the concentration of copper in a solution.  We've decided to do an EDTA titration instead of spectrophotometric analysis, but the lab is requiring us to use a murexide indicator, which we have little experience with.  I was wondering if anyone has any tips for using this indicator, especially in determining an endpoint and creating a sharp endpoint.
