REACTION OF METALS WITH WATER.
The higher the metal in the reactivity series the more reactive the metal with water.
The following experiments show the reaction of metals with cold water and water vapour/steam.
(a) Reaction of sodium/ potassium with cold water:
Put about 500cm3 of water in a beaker. Add three drops of phenolphthalein indicator/litmus solution/universal indicator solution/methyl orange indicator into the water.
