What is redox in chemistry.
In organic chemistry, redox reactions look a little different. Electrons in an organic redox reaction often are transferred in the form of a hydride ion - a proton and two electrons. Because they occur in conjunction with the transfer of a proton, these are commonly referred to as hydrogenation and dehydrogenation reactions: a hydride plus a ...
A redox is a type of chemical reaction that involves a transfer of electrons between two species. The oxidation state of an element corresponds to the number of electrons, that an atom loses, gains in a chemical reaction. The reducing agent is the reactant that is being oxidized. The oxidizing agent is reactant that is being reduced.A redox reaction is a chemical reaction in which the atoms change their oxidation numbers. Some atoms lose electrons and are oxidized – a process known as oxidation. On the other hand, some atoms gain electrons and are reduced – a process known as reduction.

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 …Because all reactions in a fuel cell consist of a fuel and an oxidizer undergoing a redox reaction, an introduction of fuel cells is at home in a discussion of redox chemistry. Figure \(\PageIndex{5}\) Fuel Cells. This fuel cell uses H 2 as the fuel and O 2 as the oxidizer. By far the most common fuel cell reaction is based on hydrogen and oxygen:Cl 2 gains one electron; it is reduced from Cl 2 to 2 Cl -; thus, Cl 2 is the oxidizing agent.
