Ba (OH) ₂ + 2HNO₃ = Ba (NO₃) ₂ + 2H₂O

Ba² ⁺ + 2OH⁻ + 2H⁺ + 2NO₃⁻ = Ba²⁺ + 2NO₃⁻ + 2H₂O

2H ⁺ + 2OH⁻ = 2H₂O

6KOH + Fe ₂ (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⁻

K ₂S + 2HCl = H₂ S + 2KCl
