WebRedox Titrations are carried out on the basis of oxidation-reduction reactions, (more commonly known as redox reactions) between the analyte and the titrant. More clearly, we can state that in a redox reaction, a reducing agent reacts with an oxidizing agent until the required results are obtained. Web21 aug. 2016 · Titrations reactions mixture must be (i) rapid; (ii) quantifiable by means of an easily observed end-point; (iii) have known and definite stoichiometry. The list is certainly not exhaustive. and of course we might, for instance, work around a slow reaction by adding an excess of titrant, and back-titrating the excess after the reaction has completed.

Web• Attach pipette filler to the pipette and hold the pipette vertically in the solution. • Do not allow the pipette to rest on the bottom of the beaker but make sure it is well below the surface to prevent air getting into the pipette. • Carefully fill the pipette to the level line and transfer the contents to a conical flask.
