Write the chemical equations for the following transformations: Na – NaOH – Na2CO3 – NaCl – Na

Let us write down the equations for the synthesis of sodium compounds:
2Na + 2H2O = 2NaOH + H2 – redox reaction (ORR), sodium hydroxide is formed;
2NaOH + CO2 = Na2CO3 + H2O – ion exchange, sodium carbonate obtained;
Na2CO3 + 2HCl = 2NaCl + CO2 + H2O – ion exchange, sodium chloride obtained;
2NaCl (melt) = 2Na + Cl2 – electrolysis, sodium is formed;
K + | Na + + e = Na | 2
A- | 2Cl – 2e = 2Cl = Cl2 | one
Sodium salts are practically used in the production of detergents.
These equations confirm the connection between metals, bases, salts.
