Potassium permanganate oxidizes oxalic acid to carbon dioxide and water. The reaction is very exothermic and the. For the five trials, three of them were room temperature, one was 10°C cooler, and the last one was 10°C warmer than the room.

Take different amounts of potassium permanganate (KMnO4) and oxalic acid (H2C2O4), and distilled water for each experiment.

The molarity for potassium permanganate isM, and oxalic acid isM. Using the medicine dropper, add a few drops of potassium permanganate to the two test tubes.

Observe how quickly the potassium permanganate solution discolours in each solution. Results. You should have seen that the the potassium permanganate discolours in the oxalic acid solution much more slowly than in the iron(II) sulfate solution.

A spectrophotometric method has been developed to study the classic permanganate–oxalate oxidation–reduction reaction.

The experiment is divided into two parts. Part I involves the determination of an unknown oxalate. This part of the experiment not only serves to quantitatively analyze oxalate by following and recording its slow bleaching effect on the absorbance. Purpose: To examine two of the factors that affect the rates of reactions; temperature and concentration, by studying the reaction between potassium permanganate and oxalic acid.

The data collected will Be both visual and computerized to increase accuracy. Kinetic Reaction Essay Sample. Abstract This experiment is to study the effect of temperature on the rate of reaction between potassium permanganate with oxalic acid. We used 2cm3 of M potassium permanganate and 4cm3 of 1M sulphuric acid into a test tube.

In another test tube, we placed 2cm3 of oxalic acid. The reaction between potassium permanganate and oxalic acid The reaction between potassium permanganate and oxalic acid O. Lidwell and R. Bell, J. Chem. Soc.,Authors contributing to RSC publications (journal articles, books or book chapters) do not need to formally request permission to reproduce material contained in.

Calculations – The strength of potassium permanganate solution in terms of molarity can be calculated by following formula – a 1 M 1 V 1 = a 2 M 2 V 2.
