СuSO4 + Fe(OH)2 ≠NiCl2 + Ba(OH)2 = Ni(OH)2↓ + BaCl2
Ni²⁺ + 2Cl⁻ + Ba²⁺ + 2OH⁻ = Ni(OH)₂↓ + Ba²⁺ + 2Cl⁻
Ni²⁺ + 2OH⁻ = Ni(OH)₂↓
6NaOH + P2O5 = 2Na3PO4 + 3H2O
6Na⁺ + 6OH⁻ + P₂O₅ = 6Na⁺ + 2PO₄³⁻ + 3H₂O
6OH⁻ + P₂O₅ = 2PO₄³⁻ + 3H₂O
H2SO4 + 2LiOH = Li2SO4 + 2H2O
2H⁺ + SO₄²⁻ + 2Li⁺ + 2OH⁻ = 2Li⁺ + SO₄²⁻ + 2H₂O
2H⁺ + 2OH⁻ = 2H₂O
Cr(OH)2 + CO2 ≠
