<P> Sodium hydroxide is also produced by combining pure sodium metal with water . The byproducts are hydrogen gas and heat , often resulting in a flame , making this a common demonstration of the reactivity of alkali metals in academic environments ; however , it is not commercially viable , as the isolation of sodium metal is typically performed by reduction or electrolysis of sodium compounds including sodium hydroxide . </P>
