Water-reactive substances - Wikipedia

Water-reactive substances are those that spontaneously undergo a chemical reaction with water, as they are highly reducing in nature. Notable examples include alkali metals, sodium through caesium, and alkaline earth metals, magnesium through barium.. Some water-reactive substances are also pyrophoric, like organometallics and sulphuric acid, and should be kept away from moisture.
