\nSodium is a highly reactive alkali metal. It reacts vigorously with cold water, producing hydrogen gas and sodium hydroxide.
\n<\/section>\n
\nThe reactivity of metals with water varies. Very reactive metals (like Group 1 alkali metals) react with cold water. Less reactive metals (like zinc or iron) may react with steam but not cold water. Even less reactive metals (like copper, silver, gold) do not react with water at all.
\n<\/section>\n
\nThe reaction of sodium with cold water is exothermic and can even ignite the hydrogen produced due to the heat generated. The general reaction is 2M + 2H\u2082O \u2192 2MOH + H\u2082 (where M is an alkali metal). Other metals like Potassium and Calcium also react with cold water, while Iron reacts with steam to produce iron oxides and hydrogen.
