Sodium reacts with water, 1 of 6. A small piece of sodium metal (Na) is dropped into a vial with water (H2O), with a drop of phenolphthalein indicator added. Sodium melts, moves around and fizzes vigorously, producing bubbles of hydrogen gas (H2) and sodium hydroxide (NaOH): Na + H2O -> NaOH + H2, and then starts to burn and even explodes. The solution turns pink in the process, indicating formation of an alkali. | |
