Answer 1

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 + 2HCl

2K+ + 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).
