MgSo4 по катиону
K2So4 не гидролизуется
А) CH3OH + C2H5COOH = H2O + C2H5COOCH3
б) (CH3COO)2Mg + 2NaOH = 2CH3COONa + Mg(OH)2
в) CH3COONH4 + KOH = CH3COOK + NH4OH
PbO + H2SO4 = PbSO4↓ + H2O
PbO + 2H⁺+SO₄²⁻ = PbSO₄↓ + H₂O
CaCO₃ + 2H⁺ + 2Cl⁻ = Ca²⁺ + 2Cl⁻ + H₂O + CO₂
CaCO₃ + 2H⁺ = Ca²⁺ + H₂O + CO₂
2. CaCl₂ = Ca + Cl₂ (электролиз)
3. 2Сa +O₂ = 2CaO
