Therefore, it takes 475 kJ of energy to make one mole of ...

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 ...Excess electrons are left behind. As a result, a negative charge is acquired on the electrode. The tendency of the metal to change into ions is known as electrolytic solution pressure. On the other hand, during reduction, metal ions in solution have a tendency to gain electrons from the electrode. So a positive charge is acquired on the electrode.

They provide insight into the overall sanitation level (positive ORP readings in the 650-750 mV range are ideal for sanitation) and life-supporting capability (above 3 mg/L DO), respectively.The measured voltage is then converted into pH or oxidation/reduction potential. Modern proves have the following components: The body of the electrode, typically made from non-conductive glass or impact resistant plastics. The reference electrode, usually comprised from the same metals as the main electrode.Key Takeaway. Chemical reactions in which electrons are transferred are called oxidation-reduction, or redox, reactions. Oxidation is the loss of electrons. Reduction is the gain of electrons. Oxidation and reduction always occur together, even though they can be written as separate chemical equations.

A classic example of the old definition of oxidation is when iron combines with oxygen to form iron oxide or rust. The iron is said to have oxidized into rust. The chemical reaction is: The iron metal is oxidized to form the iron oxide known as rust. Electrochemical reactions are great examples of oxidation reactions.
