What is oxidation reduction potential.
ORP stands for oxidation-reduction potential and is measured in millivolts or mV. In general terms ORP refers to a substance's ability to oxidize another agent resulting in a positive mV reading, or reduce another agent resulting in a negative mV reading. Most water has a positive ORP rating making it an oxidizing agent which is why it's ...
They must exhibit a redox potential lower than that of the compound that they want to protect, i.e., they must be oxidized first than the protected agent. 21-23.

ORP is a measurement, in millivolts (mV), of the water's potential for oxidizers to steal electrons from another substance. In the pool industry, chlorine is usually the primary oxidizer, and contaminants like metals, ammonia, and non-living organics are the targets of oxidation.
To evaluate a potential oxidation-reduction reaction, scientists first break the reaction into half reactions, which represent the loss of electrons, or reduction.

For example, water may be moderately oxidizing (such as aerated water), strongly oxidizing (such as chlorinated water or hydrogen peroxide solution), or reducing (such as an environment where anaerobic microbes are active).
Oxidation-reduction potential (ORP) measures the ability of a lake or river to cleanse itself or break down waste products, such as contaminants and dead plants and animals. When the ORP value is high, there is lots of oxygen present in the water. This means that bacteria thatLike 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.The redox potential (Eh) is defined as the emf or potential of an electrode consisting of a redoxcouple (e.g., SO 4 2 − / H 2 S) measured in a galvanic cell against the standard hydrogen electrode. Eh in soils generally ranges between −1 and +1 V.Oxidation reduction potential is measured on a voltage scale in the range of millivolts when it comes to its measurement in water.
