So an oxidising agent must gain electrons.
The amount or rate by which something is reduced,.g.

Gain of hydrogen In certain cases, a reduction can also be described as the gain of hydrogen atoms in going from reactant to product.Consider, for example, the net-ionic equation (the equation showing just the chemical substances that are changed during a reaction) for a reaction with zinc metal and an aqueous copper(II) sulfate solution: cadeau pour mariage argent This overall reaction is really composed of two half-reactions, shown below.English, noun ( en-noun the act, process, or result of reducing.Questions on redox definitions answers, where would you like to go now?(See phenomenological reduction.) (medicine) A medical procedure to restore a fracture or dislocation to the correct alignment.Understanding is a lot safer than thoughtless learning!Reduction is gain of electrons (OIL RIG).Both the oxidizing and reducing agents are on the left (reactant) side of the redox equation.Methyl alcohol (wood alcohol) can be oxidized to formaldehyde: In going from methanol to formaldehyde, the compound went from having four hydrogen atoms to having two hydrogen atoms.The argument (going on inside your head) would go like this if you wanted to know, for example, what an oxidising agent did in terms of electrons: An oxidising agent oxidises something else.But without that copper cation (the oxidizing agent ) present, nothing will idée cadeau de mariage pour mes parents happen.Loss of hydrogen, in other reactions, oxidation can best be seen as the loss of hydrogen.The following equation shows sodium losing the electron: When it loses the electron, chemists say that the sodium metal has been oxidized to the sodium cation.(cooking) The process of rapidly boiling a sauce to concentrate.Like oxidation, there are three definitions you can use to describe reduction: The gain of electrons, the loss of oxygen, the gain of hydrogen.A second point to keep in mind is that oxidation states are bookkeeping tools only.For example, when sodium metal reacts with chlorine gas to form sodium chloride (NaCl the sodium metal loses an electron, which is then gained by chlorine.Oxidation is loss of electrons (OIL RIG).
