1)NaOH+HCl=NaCl+H2O
2NaOH+CuCl2=2NaCl+Cu(OH)2
2)BaCl2+H2SO4=BaSO4+2HCl
BaCl2+NaSO4=BaSO4+NaCl2
3)CuSO4+2HCl=2CuCl2+H2SO4
CuO+2HCl=CuCl2+H20
1) 2CH₃COOH+Na₂SiO₃ ⇒ 2CH₃COONa+H2SiO₃
2CH₃COO⁻+2H⁺+2Na⁺+SiO₃⁻² ⇒ 2CH₃COO⁻+2Na⁺+H₂SiO₃↓
2H⁺+SiO₃⁻²⇒H₂SiO₃↓
2CH₃COOH+Na₂CO₃⇒2CH₃COONa+H₂O+CO₂↑
2CH₃COO⁻2H⁺+2Na⁺+CO₃²⁻⇒2CH₃COO⁻+2Na⁺+H₂O+CO₂↑
2H⁺+CO₃²⁻⇒H₂O+CO₂↑
2CH₃COOH+CuO⇒(CH₃COO)₂Cu+H₂O
2CH₃COO⁻+2H⁺+CuO⇒2CH₃COO⁻+Cu²⁺+H2O
2H⁺+CuO⇒Cu²⁺+H2O
2СH₃COOH + Zn => (CH₃COO)₂Zn + H₂↑
2CH₃COO⁻ + 2H⁺ + Zn => 2CH₃COO⁻ + Zn²⁺ + H₂↑
2H⁺ + Zn => Zn²⁺ + H₂↑
