How is Sodium Carbonate Formed: When the strong base sodium hydroxide reacts with acid Carbonic acid, Sodium carbonate is obtained. It is a neutralisation reaction.
Since the reaction is between a strong base and weak acid, the salt formed is alkaline.
The solution of sodium carbonate turns the litmus paper from red to blue.
When sodium hydrogen Carbonate is heated, it decomposes to form sodium carbonate.
Sodium carbonate which does not contain any water of crystallization is called a hydrous sodium carbonate.Anhydrous sodium carbonate is also known as soda ash.
When soda ash is dissolved in water and recrystallized, crystal of washing soda is formed.
Generally metallic Carbonate are insoluble in water, but sodium carbonate is soluble in water. Sodium Carbonate does not contain any replaceable hydrogen atom, it is a normal salt.
When Sodium Carbonate reacts with dilute acids, the products formed a Sodium chloride, carbon dioxide and water.
Soidum Carbonate Na2CO3.10 H2o Uses (washing soda):1. Uses as a detergent for washing clothes.
2. Used to remove the permanent hardness of water.
3. Used in the manufacture of sodium component such a borax.
