Web27 Oct 2024 · A small piece of sodium metal will be placed in a bowl of water. If a phenolphthalein indicator has been added to the water, the sodium will leave a pink trail behind it as the metal sputters and reacts. The reaction is: 2 Na + 2 H 2 O → 2 Na + + 2 OH - + H 2 (g) The reaction is especially vigorous when warm water is used.
