WebOxidation–reduction reactions, commonly known as redox reactions, are reactions that involve the transfer of electrons from one species to another. The species that loses electrons is said to be oxidized, while the species that gains electrons is said to be reduced. WebWhen a metal reacts with water, a metal hydroxide and hydrogen are formed. For example, sodium reacts rapidly with cold water: Sodium + water → sodium hydroxide + hydrogen … WebThe displacement reactions of metals A chemical is described as being reactive if it takes part easily and quickly in chemical reactions .
