In chemistry, the term ''base metal'' is used informally to refer to a metal that oxidizes or corrodes relatively easily, and reacts variably with dilute hydrochloric acid (HCl) to form hydrogen.Examples include iron, nickel, lead and zinc.Copper is considered a base metal as it oxidizes relatively easily, although it does not react with HCl.
Hydride - Wikipedia
Hydrogen gas is liberated in a typical acid-base reaction. NaH + H 2 O → H 2 (g) + NaOH ΔH = −83.6 kJ/mol, ΔG = −109.0 kJ/mol Often alkali metal hydrides react with metal halides. Lithium aluminium hydride (often abbreviated as LAH) arises from reactions .
