1) 2CH3COOH + CuO = (CH3COO)2Cu + H2O (условия: t)
2CH3COOH + CuO = 2CH3COO⁻ + Cu²⁺ + H2O
2) 2CH3COOH + Na2CO3 = 2CH3COONa + CO2 + H2O
2CH3COOH + 2Na²⁺ + CO3²⁻ = 2CH3COO⁻ + 2Na⁺ + CO2 + H2O
2CH3COOH + CO3²⁻ = 2CH3COO⁻ + CO2 + H2O
3) 2CH3COOH + Mg = (CH3COO)2Mg + H2
2CH3COOH + Mg⁰ = 2CH3COO⁻ + Mg²⁺ + H2
