What is redox.
13 Points. Because the `H` attached with C in CH4 is getting separated. Whenever there is removal of H we term it as reduction .Also, O2 is being attached with the C which inturn is termed as oxidation.So, since oxidation and reduction both are taking place in this rxn. , it is a redox reaction.

The oxidation state of carbon increases from +2 to +4, while the oxidation state of the hydrogen decreases from +1 to 0. Oxidation and reduction are therefore best defined as follows. Oxidation occurs when the oxidation number of an atom becomes larger. Reduction occurs when the oxidation number of an atom becomes smaller.The redox potential, or more accurately the reduction potential, of a compound refers to its tendency to acquire electrons and thereby to be reduced. Some readers might remember the mnemonic “OILRIG” which reminds us that “oxidation is loss, reduction is gain”, where the loss and gain are of electrons. Consider a reaction that involves ...Redox Titration Curves. To evaluate a redox titration we need to know the shape of its titration curve. In an acid-base titration or a complexation titration, the titration curve shows how the concentration of H 3 O + (as pH) or M n + (as pM) changes as we add titrant. For a redox titration it is convenient to monitor the titration reaction's potential instead of the concentration of one ...
