Reaction d'oxydo-reduction
An oxidant is a chemical species that gains electrons, while a reducer is a chemical species that loses electrons.
Demi Equation
Reduction (e-)
Ox + ne- = Red
Oxydation (e-)
Red = Ox + ne-
Titrage Oxydoreduction Exercice
The principle of titration involves filling the graduated burette with the titrant solution and then transferring it into a beaker containing the reactant solution using a pipette. An Erlenmeyer flask, magnetic stir bar, and magnetic stirrer are used in the protocol. The titration is carried out drop by drop until the equivalence point is reached, indicating complete consumption of the reactants and the attainment of a stoichiometric mixture.
Couple Redox
The redox couple can be determined using the equation: M + ne- = nxM, where M represents a cation, ne- denotes the number of electrons transferred, and nxM indicates the product formed after the redox reaction.
Dosage Potentiometrique
The dosage potentiometric of Fe2+ by Ce4+ involves using the equation CE4+/CE3+ redox potential and V = nFe2+/nCe4+ to determine the concentration of the Fe2+ species.
