In aqueous solutions, redox potential is a measure of the tendency of the solution to either gain or lose electrons in a reaction. A solution with a higher (more positive) reduction potential than some other molecule will have a tendency to gain electrons from this molecule (i.e. to be reduced by oxidizing this other molecule) and a solution with a lower (more negative) reduction potential ...
2,6-Dichlorophenolindophenol (DCPIP, DCIP or DPIP) is a chemical compound used as a redox dye. When oxidized, DCPIP is blue with a maximal absorption at 600 nm; when reduced, DCPIP is colorless. DCPIP can be used to measure the rate of photosynthesis. It is part of the Hill reagents family. When exposed to light in a photosynthetic system, the ...

It is a redox reaction in which metallic sodium gives an electron to a proton of ammonia which is reduced in hydrogen gas. Sodium easily dissolves in liquid ammonia to produce solvated electrons responsible for the blue color of the resulting liquid. The Na + and NH − 2 ions are produced by this reaction.
Illustration of a redox reaction Sodium chloride is formed through the redox reaction of sodium metal and chlorine gas. Redox reactions can be understood in terms of the transfer of electrons from one involved species (reducing agent) to another (oxidizing agent). In this process, the former species is oxidized and the latter is reduced. Though ...
This is often seen in redox titrations when the different oxidation states of the product and reactant produce different colors. Precipitation: If a reaction produces a solid, a precipitate will form during the titration. A classic example is the reaction between Ag + and Cl − to form the insoluble salt AgCl. Cloudy precipitates usually make ...
EC 1, Oxidoreductases: catalyze oxidation/reduction reactions; EC 2, Transferases: transfer a functional group (e.g. a methyl or phosphate group) EC 3, Hydrolases: catalyze the hydrolysis of various bonds; EC 4, Lyases: cleave various bonds by means other than hydrolysis and oxidation; EC 5, Isomerases: catalyze isomerization changes within a ...
Redox reactions are prevalent for the transition elements. Two classes of redox reaction are considered: atom-transfer reactions, such as oxidative addition/reductive elimination, and electron-transfer. A fundamental redox reaction is "self-exchange", which involves the degenerate reaction between an oxidant
