Organic titration
Witryna1 lis 2004 · In direct titration, the non-reduced excess of dichromate is detected. However, if back titration is used, FeSO 4 is added to the sample after oxidation, followed by titration with dichromate. Direct titration is more reliable, whereas back titration is prone to carbon overestimation [27].

Once the rate law of a reaction is determined the same law can be used to understand the composition of the reaction mixture completely. In other words, the reaction order is the exponent to which the concentration of the …
