Ba(OH)₂ + 2HNO₃ = Ba(NO₃)₂ + 2H₂OBa²⁺ + 2OH⁻ + 2H⁺ + 2NO₃⁻ = Ba²⁺ + 2NO₃⁻ + 2H₂O
2H⁺ + 2OH⁻ = 2H₂O
6KOH + Fe₂(SO₄)₃ = 2Fe(OH)₃↓ + 3K₂SO₄
6K⁺ + 6OH⁻ + 2Fe³⁺ + 3SO₄²⁻ =2Fe(OH)₃↓ + 6K⁺ + 3SO₄²⁻
6OH⁻ + 2Fe³⁺ = 2Fe(OH)₃↓
Cu(OH)₂ + 2H⁺ = Cu²⁺ + 2H₂O
Cu(OH)₂ + 2H⁺ + 2Cl⁻ = Cu²⁺ +2Cl⁻ + 2H₂O
Cu(OH)₂ + 2HCl = CuCl₂ + 2H₂O
S²⁻ + 2H⁺ = H₂S
2K⁺+ S²⁻ +2H⁺ + 2Cl⁻ = H₂S + 2K⁺ + 2Cl⁻
K₂S +2HCl = H₂S + 2KCl
