Н2SO4→ SO2→ SO3→ NaHSO4→Na2SO4→BaSO4

Question

Н2SO4→ SO2→ SO3→ NaHSO4→Na2SO4→BaSO4

Answer 1

SCl2 + H2SO4= 2SO2 + 2HCl
2SO2 + O2 = 2SO3
NaOH + SO3 = NaHSO4
NaHSO4 + NaOH(конц.) = Na2SO4 + H2ONa2SO4 + BaX2 = BaSO4↓ + 2NaX

Comments

NaHSO4 + NaOH(конц.) = Na2SO4 + H2O

---

Na2SO4 + BaX2 = BaSO4↓ + 2NaX
