Caption: Demonstration of an experiment showing the reaction of sodium with water. In this image a lump of the soft, grey metal is being extracted from the beaker at left. It has been stored under oil to prevent reaction with atmospheric moisture. When the sodium is dropped into the beaker of water (right) a violent exothermic reaction occurs in which the sodium reduces the water to hydrogen (given off as a gas) & combines with liberated hydroxyl ions to produce sodium hydroxide (a weak alkali). Sodium belongs to the group of alkali metals situated in group 1 of the periodic table.
