What happens when potassium permanganate is standardized with ethanedioic acid?
When potassium permaganate is mixed with ethanedioc acid the potassium permanganate Mn04- ion will be converted toMn2+, this means that you will observe the purple colour changing to a clear solution and the permanganate ion is oxidised. The Mn2+ will act as an auto catalyst speeding up the reaction, therefore a funny rate will occur, where the reaction is slow to start, before speeding up and slowing down again at the end. I read about this in chemistry review, so you can check it out there...http://www.york.ac.uk/depts/chem/chemrev/autocat.doc.

To act as a catalyst
What is meant by internal indicator?
Sometimes one of the reactants in a titration act as an indicator; this is an internal indicator. An example is the volumetric technique of permanganometry.
Is Cu an oxidizing agent?
I'm almost certain that it can be used as an oxidizing agent. It is not as strong persay as Potassium permanganate, but depending on to what extent you are oxidizing something, that may be a good thing.
Which test is the best indicator of how well you do on the act?
Aspire.

Do all people act out at self interest?
All people act out of self interest at one time or another, but some people act out of self interest most, if not all, of the time. People who act out of self interest regardless of how their actions affect others often have psychological issues or are extremely selfish.
