What is NaHCO3? Important knowledge about NaHCO3.

Definition of NaHCO₃
NaHCO₃, also known as Sodium bicarbonate or Bicarbonate of soda, is an inorganic chemical compound with the formula NaHCO₃. NaHCO₃ is a white, odorless solid, which has a salty taste and is capable of polarizing water. NaHCO₃ has a molecular mass of 84.007 g/mol. The NaHCO₃ molecule consists of a sodium ion Na+, and a bicarbonate ion HCO₃-. The bicarbonate ion HCO₃- is formed from a carbonate ion CO₃₂- that has received a proton H+.

Properties: NaHCO₃
2.1 Physical properties of NaHCO₃: NaHCO₃ is a white, odorless solid with a salty taste and a pH of about 8.5, indicating its weak alkaline nature.
2.2 Chemical properties of NaHCO₃: NaHCO₃ can react with acid to produce CO₂ gas, water, and salt. NaHCO₃ can also react with alkali to produce carbonate, water, and salt.

Common chemical equations of NaHCO₃:
NaHCO₃ + HCl -> NaCl + CO₂ + H₂O
NaHCO₃ + NH₄Cl -> NH₄HCO₃ + NaCl
NaHCO₃ + H₂SO₄ -> Na₂SO₄ + CO₂ + H₂O
NaHCO₃ + CH₃COOH -> CH₃COONa + CO₂ + H₂O
NaHCO₃ + H₃PO₄ -> Na₃PO₄ + CO₂ + H₂O

Preparation of NaHCO₃
4.1 Laboratory preparation of NaHCO₃: NaHCO₃ can be prepared from the reaction of Na₂CO₃ with CO₂ and H₂O.
Na₂CO₃ + CO₂ + H₂O -> 2NaHCO₃
4.2 Industrial preparation of NaHCO₃: In industry, NaHCO₃ is usually produced by saturating a solution of sodium carbonate (Na₂CO₃) with CO₂.
