Write the reaction equations: Sodium = Sodium hydroxide = Sodium sulfide = Sodium chloride = Sodium sulfate = Barium sulfate

To carry out transformations along the above chain, we need to carry out four reactions. To carry out the first, you need to mix water and sodium, as a result of the reaction, sodium hydroxide is formed and hydrogen is released.

2Na + 2H2O = 2NaOH + H2.

for the second reaction, add sodium hydrosulfide to sodium hydroxide. The chemical equation for the reaction looks like this:

NaHS + NaOH = Na2S + H2O as a result of the reaction, sodium sulfide and hydrogen sulfide are formed.

the third reaction is carried out by mixing sodium sulfide and hydrochloric acid, sodium chloride and hydrogen sulfide are formed.

Na2S + 2HCl = 2NaCl + H2S

the fourth reaction penetrates when sodium hydrogen sulfate is added to table salt

NaCl + NaHSO4 = Na2SO4 + HCl as a result of the reaction, sodium sulfate and hydrochloric acid are formed.
