To carry out the above chain of transformations, it is necessary to carry out the following reactions:
The reaction between sodium and water as a result of the reaction, sodium hydroxide is formed and hydrogen is released.
2 Na + 2 H2O = 2 NaOH + H2 ↑
Sodium hydroxide react with sulfuric acid as a result of the reaction, sodium sulfate is formed and water is released.
2 NaOH + H2SO4 = Na2SO4 + 2 H2O
Sodium sulfate react with calcium chloride as a result of the reaction, calcium sulfate and sodium chloride are formed.
Na2SO4 + CaCl2 = CaSO4 ↓ + 2 NaCl.
