Sodium Hydrogen Carbonate
Sodium hydrogen carbonate is a chemical compound that has consists of a sodium cation and a bicarbonate anion. The mineral has a slightly alkaline taste but offers appears as a fine powder. It is weakly basic oxidizing agent. It is an alkali metal salt and has a high reactivity with water. The systematic IUPAC name is known as sodium hydrogen carbonate. The chemical or molecular formula of sodium hydrogen carbonate is NaHCO3. It is also known as baking soda or bicarbonate of soda.
Structural Formula
This is the structural formula of the sodium hydrogen carbonate:
Molecular Formula
The chemical formula of the sodium hydrogen carbonate is NaHCO3. It has consists of one sodium and two oxygen atoms.
How it Can Be Prepared
It can be prepared by the reaction of sodium chloride is treated along with the water and carbon dioxide and it gives the product of sodium bicarbonate and byproduct is the hydrochloric acid. It is an alkaline and could be used in the baking powder to avoid a metallic taste. It slowly reacts at the room temperatures. It can be decomposed at above the threshold limit. The following chemical reaction is given as follows.
Na2CO3 + H2O + CO2 → 2 NaHCO3 + HCl
