Nickel reduction is a chemical reaction in which nickel is used to reduce a metal ion to its elemental form, typically by donating electrons.
Nickel can reduce a wide range of metals, including copper, silver, gold, zinc, lead, and iron.
Nickel has a high affinity for electrons, meaning it readily donates electrons to other metals. This transfer of electrons leads to the reduction of the metal ion to its elemental form.
While nickel can reduce many metals, there are some limitations. For example, it cannot reduce metals that are more reactive than nickel, such as alkali metals.
Nickel reduction has many industrial applications, including electroplating, catalysts in chemical reactions, and the production of alloys.
