Sodium and water, in absence of air or oxygen, react to produce hydrogen gas and sodium hydroxide.
When there is a slight amount of oxygen in the reaction mixture this will immediately and explosively react with hydrogen to form water. That's why this is a dangerous reaction.
The word equations for the reactions of sodium with oxygen are: "sodium + oxygen → sodium oxide" and "sodium + oxygen → sodium peroxide." The chemical equation for the formation of sodium oxide is 4Na + O2 → 2Na2O, and for the formation of sodium peroxide is 2Na + O2 → Na2O2. These reactions illustrate the different oxidation states of sodium when it reacts with oxygen.
The pale grey coating on sodium is sodium oxide (Na2O) or sodium hydroxide (NaOH) that forms when sodium reacts with oxygen or moisture in the air.
Sodium iodide
The chemical name for Sodium Hydrogen Carbonate is sodium bicarbonate.
Na is the chemical symbol for sodium. Na is from the word natrium, which is Latin for sodium carbonate.
The chemical name for sodium is Na and for oxygen is O. When combined, they form sodium oxide (Na2O).
This compound is sodium carbonate - Na2CO3.
The chemical name for Na1O2 is sodium peroxide. It is a compound composed of sodium and oxygen in a 1:2 ratio.
The word equations for the reactions of sodium with oxygen are: "sodium + oxygen → sodium oxide" and "sodium + oxygen → sodium peroxide." The chemical equation for the formation of sodium oxide is 4Na + O2 → 2Na2O, and for the formation of sodium peroxide is 2Na + O2 → Na2O2. These reactions illustrate the different oxidation states of sodium when it reacts with oxygen.
Sodium Oxide= Na2O
Sodium hydroxide contains sodium, oxygen and hydrogen.
NaHCO3 is sodium bicarbonate. NaC2H3O2 is sodium acetate.
Sodium carbonate contains the elements sodium, carbon, and oxygen. Its chemical formula is Na2CO3.
The chemical name of sodium chloride is sodium chloride. The formula is NaCl.
The pale grey coating on sodium is sodium oxide (Na2O) or sodium hydroxide (NaOH) that forms when sodium reacts with oxygen or moisture in the air.
The chemical equation for sodium reacting with oxygen to produce sodium oxide is: 4Na + O2 -> 2Na2O
