What is the molarity of a K2SO3 solution if 25.0ml of it was oxidized by 30.0ml of 0.450M KMnO4 aqueous solution?
Molarity=moles of solution /liters of solution

Redox reactions are a family of reactions that are concerned with the transfer of electrons between species. Like acid-base reactions, redox reactions are a matched set -- you don't have an oxidation reaction without a reduction reaction happening at the same time. Oxidation refers to the loss of electrons, while reduction refers to the gain of electrons. Each reaction by itself is called a "half-reaction", simply because we need two (2) half-reactions to form a whole reaction. This problem illustrates the methodology in a titration experiment.
