Burning of sodium in air observation and chemical reaction. |
|
Answer» Sodium reacts with the oxygen in air to form sodium oxide, and traces of YELLOWISH sodium peroxide. 4Na+O2→2Na2O 2Na2O+O2→2Na2O2 The sodium oxide formed will REACT with WATER to give sodium hydroxide. Na2O+H2O→2NaOH The sodium hydroxide formed will react with carbon dioxide to give sodium carbonate, which is RELATIVELY unreactive to the atmosphere, barring the hygroscopicity. 2NaOH+CO2→Na2CO3+H2O |
