Ethene, for example, is oxidised to ethane-1,2-diol. Redox titrations help us find the exact amount of an oxidising agent needed to react with a reducing agent. My source is as follows: Kovacs K.A. Oxalic acid salts contain the ethanedioate ion (C2O42-). In the test-tube, the colour changes are: I have shown the original solution as very pale pink (the palest I can produce! Potassium manganate(VII) will react with acidified ethanedioate ions as detailed by the following equation: To determine the rate of reaction some of the reaction mixture can be removed, and any unreacted manganate(VII) ions can oxidise iodide ions to form free iodine, stopping the reaction shown above, The iodine formed can then be titrated with sodium thiosulfate, using starch as an indicator, This is the most common practical method of recording the rate of reaction for Mn as the autocatalyst in the reaction between ethanedioic acid and acidified potassium manganate(VII), Swirl the reaction mixture and start the stop watch, Repeat every 30 seconds to remove 10.0 cm, The volume of the titre of thiosulfate used in each titration will be proportional to the concentration of manganate(VII) ions in the reaction mixture at the time the reaction mixture was stopped (by adding it to the potassium iodide solution), The rate of reaction is slow to start with, then speeds up, before slowing down and stopping, Initially the reaction is slow, however one of the products is Mn, Therefore, as the reaction continues more catalyst is released and the reaction reaches its maximum rate of reaction, Then as the concentration of potassium manganate(VII) continues to decrease, the rate also decreases, Instead of monitoring this reaction by removing samples and titrating with sodium thiosulfate, colorimetry can be used, The absorption of light is dependent on the concentration of potassium manganate(VII), and some data loggers can be used in conjunction with a colorimeter producing a graph (absorption against time) directly without any calculation.
