Heya. I am doing my chemistry coursework on the reaction between potassium permangate and oxalic acid - and i am looking at the difference that changing the concentrations of the oxalate ions and manganate (vii) ions will have to the reaction, and also changing the temperature of the reaction, and the catalysts in the reaction. I have found out that it is a autocatalytic reaction, but i dont know what the catalyst is? is it the carbon dioxide or not? please can someone help me becuase i am going out of my mind with worry!!
what concentrations do i need to try for the oxalate and the pott perm? and what temperature range should i use - and how do i change the temperature(seeing as i am doing a titration?!)
thankyou so much guys..

p.s. i also need to be able to work out the rate of reaction using a calibration curve.. if anyone wants to be so kind as to help me.. drop me a message!

The catalyst is Mn2+. Manganese can jump up and down between a lot of different oxidation states, which helps the electron transfer which lies at the heart of any redox reaction.
Changing the temperature for a titration in a controlled manner is not very easy unless you have the right equipment.
I am not sure how broadly you are looking into this reaction, but I think that if you try it under acidic, neutral, and alkaline conditions, you might notice some interesting differences.
Have fun!

the proportion errors for the gasoline syringe its relative to the fee u measured. u can locate it via dividing the "absolute errors" (e.g. the smallest subject you may degree or what a "era" interior the syringe equals - could be around 0.1ml) via the interpreting value you have. working example, in case you got a volume value of 25ml you share errors would be errors = (0.a million/25)*a hundred = 0.4% in case you have a decrease volume value, the errors will substitute into greater considerable.... (i recent in my cwk that lots of the errors the place from gasoline loses....) sturdy success!
