The reaction between sodium and oxygen

Sodium + Oygen Sodium oxide
4Na + O2 2Na2O


 When heated sodium produces a yellow flame

Sodium burns with a bright yellowy orange flame. Once burnt, the sodium oxide left is a white colour. Sodium oxide is soluble in water and forms sodium hydroxide with a pH of between 13 and 14 (a very strong alkali).
