1) Образование воды.
NaOH + HCl = NaCl + H2O
CaCO3 + 2HCl = CaCl2 + CO2 + H2O
2) Образование осадка.
AgNO3 + HCl = AgCl + HNO3
AlCl3 + 3NaOH = Al(OH)3 + 3NaCl
3) Образование газа.
Na2CO3 + 2HCl = 2NaCl + CO2 + H2O
Mg + 2HCl = MgCl2 + H2
KOH + HNO₃ = KNO₃ + H₂O
2KOH + H₂SO₄ = K₂SO₄ = 2H₂O
KOH + CuCl = CuOH + KCl
Al⁺³₂O⁻²₃, Ag⁺Cl⁻¹,Fe⁺²Cl⁻¹₂
2NaOH+H2SO4=Na2SO4+2H2O
2LiOH+CuSO4=Li2SO4+CuOH2
2NaOH+ZnO=Na2ZnO2+H2O
4 HNO3 + Cu = Cu(NO3)2 + 2 NO2 + 2 H2O
