NiSO4 + 2NaOH = Ni(OH)2 + Na2SO4
Ni(2+) + SO4(2-) + 2Na+ + 2OH- = Ni(OH)2 + 2Na+ + SO4(2-)
Ni(2+) + 2OH- = Ni(OH)2
AlCl3 + 3NaOH = Al(OH)3 + 3NaCl
Al(3+) + 3Cl- + 3Na+ + 3OH- = Al(OH)3 + 3Na+ + 3Cl-
Al(3+) + 3OH- = Al(OH)3
CuSO4 + 2NaOH = Cu(OH)2 + Na2SO4
Cu(2+) + SO4(2-) + 2Na+ + 2OH- = Cu(OH)2 + 2Na+ + SO4(2-)
Cu(2+) + 2OH- = Cu(OH)2
Ni(OH)2 + 2HCl = NiCl2 + 2H2O
Ni(OH)2 + 2H+ +2Cl- = Ni(2+) + 2Cl- + 2H2O
Ni(OH)2 + 2H+ = Ni(2+) + 2H2O
Al(OH)3 + 3HCl = AlCl3 + 3H2O
Al(OH)3 + 3H+ + 3Cl- = Al(3+) + 3Cl- + 3H2O
Al(OH)3 + 3H+ = Al(3+) + 3H2O
Cu(OH)2 + 2HCl = CuCl2 + 2H2O
Cu(OH)2 + 2H+ + 2Cl- = Cu(2+) + 2Cl- + 2H2O
Cu(OH)2 + 2H+ = Cu(2+) + 2H2O
K2Cr2O7 + 2BaCl2 + H2O = 2BaCrO4 + 2KCl + 2HCl2K+ + Cr2O7(2-) + 2Ba(2+) + 4Cl(-) + H2O = 2BaCrO4 + 2K+ + 2Cl- + 2H+ + 2Cl-
2K+ + Cr2O7(2-) + 2Ba(2+) + 4Cl(-) + H2O = 2BaCrO4 + 2H+
Pb(CH3COO)2 + 2KI = PbI2 + 2CH3COOK
Pb(2+) + 2CH3COO- + 2K+ + 2I- = PbI2 + 2CH3COO- + K+
Pb(2+) + 2I- = PbI2
Ca(OH)2 + CO2 = CaCO3 + H2O
Ca(2+) + 2OH- + CO2 = CaCO3 + H2O
CaCO3 + CO2 + H2O = Ca(HCO3)2
Ca(2+) + CO3(2-) + CO2 + H2O = Ca(2+ ) + 2HCO3(-)
CO3(2-) + CO2 + H2O = 2HCO3(-)
CoCl2 + NaOH = CoClOH + NaCl
Co(2+) + 2Cl- + Na+ + OH- = CoClOH + Na+ + Cl-
Co(2+) + Cl- OH- = CoClOH
CoCl2 + 2NaOH = Co(OH)2 + 2NaCl
Co(2+) + 2Cl- + 2Na+ + 2OH- = Co(OH)2 + 2Na+ + 2Cl-
Co(2+) + 2OH- = Co(OH)2
Co(OH)2 + 2HCl = CoCl2 + 2H2O
Co(OH)2 + 2H+ +2Cl- = Co(2+) + 2Cl- + 2H2O
Co(OH)2 + 2H+ = Co(2+) + 2H2O
4Co(OH)2 + O2 + 2H2O = 4Co(OH)3 (ионов нет - ни одно из соединений не диссоциирует).
