Reaction with WaterSome metals react with water to produce metal hydroxide and hydrogen gas. Generally non-metals do not react with water
a) Active metals like Na, K react with water at room temperature.
The reaction is so violent and exothermic that the evolved hydrogen catches fire.
b) Less active metals like Mg , Zn , Al , react with boiling water.
c) Metals like Fe, Ni react very mildly with steam.
