Ba(OH)2 + 2HCl = BaCl2 + 2H2O
Ba²⁺+2OH⁻+2H⁺+2Cl⁻ = Ba²⁺+2Cl⁻+2H₂O
2H⁺+2OH⁻=2H₂O
MgCl₂+(NH₄)₂CO₃ = MgCO₃↓+2NH₄Cl
Mg²⁺+2Cl⁻+2NH₄⁺+CO₃²⁻ = MgCO₃↓+2NH₄⁺+2Cl⁻
Mg²⁺+CO₃²⁻=MgCO₃↓
FeBr₃ + 3LiOH = Fe(OH)₃↓ + 3LiBr
Fe³⁺ + 3Br⁻ + 3Li⁺ + 3OH⁻ = Fe(OH)₃↓ + 3Li⁺ + 3Br⁻
Fe³⁺ + 3OH⁻ = Fe(OH)↓
CuCl₂ + Na₂S = CuS↓ + 2NaCl
Cu²⁺+2Cl⁻+2Na⁺+S²⁻ = CuS↓ + 2Na⁺+2Cl⁻
Cu²⁺+S²⁻=CuS↓
MnCl₂+Na₂S = MnS↓+2NaCl
Mn²⁺+2Cl⁻+2Na⁺+S²⁻ = MnS↓+2Na⁺+2Cl⁻
Mn²⁺+S²⁻=MnS↓
