One of the key types of “transformations” is oxidation-reduction processes.
WebLike other chemical reactions, redox reactions involve a free energy change. Reactions that move the system from a higher to a lower energy state are spontaneous and release energy, while those that do the opposite require an input of energy. In redox reactions, energy is released when an electron loses potential energy as a result of the transfer. WebORP is not referred to any separate redox couple and represents a compromise for all redox reactions occur ring in water. In laboratory practice the ORP measurements make use of the test platinum electr ode in a pair with refer ence silver–chloride electrode (SCE), the potential of which is by 0.2224 V more positive than that of NHE.
