Answer 1

Hey user...


sodium metal react with water to form sodium oxide which further dissolve in water to give sodium hydroxide solution .

aluminium reacts with oxygen to form Aluminium oxide which does not dissolve in water to form aluminium hydroxide .
the metals placed lower in the reactivity series are less reactive towards water .
