In this task you will need to write down the chemical reaction equations for the next chain of compounds.
Na – NaCl – Na2CO3 – NaHCO3 – Na2CO3.
1. The reaction of obtaining sodium chloride.
2Na + 2HCl = 2NaCl + H2.
The reaction is called an exchange reaction.
2. The reaction of obtaining sodium carbonate.
2NaCl + H2CO3 = Na2CO3 + 2HCl.
The reaction is called the sodium carbonate and hydrochloric acid reaction.
3. The reaction of obtaining sodium bicarbonate.
Na2CO3 + CO2 + H2O = 2NaHCO3.
The reaction is called a compound reaction.
4. The reaction of obtaining sodium carbonate.
2NaHCO3 = (t) Na2CO3 + H2O + CO2.
The reaction is called a decomposition reaction.
