Make a reaction equation: sodium-sodium hydroxide-sodium sulfide-sodium chloride-sodium sulfate

univerkov | June 26, 2021 | education

Na → NaOH → Na2S → NaCl → Na2SO4

1) 2Na + 2H2O → 2NaOH + H2 ↑ (substitution reaction; sodium, water, sodium hydroxide, hydrogen);

2) 2NaOH + H2S → Na2S + 2H2O (exchange reaction; sodium hydroxide, hydrogen sulfide, sodium sulfide, water);

3) Na2S + CaCl2 → 2NaCl + CaS (exchange reaction; sodium sulfide, calcium chloride, sodium chloride, calcium sulfide);

4) 2NaCl + CaSO4 → Na2SO4 + CaCl2 (exchange reaction; sodium chloride, calcium sulfate, sodium sulfate, calcium chloride).

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
