Na2CO3+2HCl=2NaCl+2H2CO3-->2H2O 2CO2
2Na+ + (CO3)2- +2H+ + 2Cl- = 2Na+ 2Cl- + 2H2O + 2CO2
(CO3)2- + 2H+ = 2H2O + 2CO2
3KOH+H3PO4=K3PO4+3H2O
3K+ + 3OH- + 3H+ + (PO4)3- = 3K+ + (PO4)3- + 3H2O
3OH- + 3H+ = 3H2O
2NaOH+H2SO4=Na2SO4+2H2O
2Na+ + 2OH- + 2H+ (SO4)2- = 2Na+ + (SO4)2- +2H2O
2OH- + 2H+ = 2H2O
NaOH+HCl=NACl+H2O
Na+ + OH- + H+ + Cl- = Na+ + Cl- + H2O
OH- + H+ = H2O
CuSO4+2NaOH=Cu(OH)2 (осадок) + Na2SO4
Cu2+ + (SO4)2- + 2Na+ + 2OH- =Cu(OH)2 (осадок) + 2Na+ + (SO4)2-
Cu2+ + 2OH- =Cu(OH)2 (осадок)
ZnCl2+2KOH=Zn(OH)2 (осадок) +2KCl
Zn2+ + 2Cl- + 2K+ + 2OH- =Zn(OH)2 (осадок) + 2K+ + 2Cl-
Zn2+ + 2OH- =Zn(OH)2 (осадок)
NH4Cl+NaOH=NH4OH(осадок) +NaCl
NH4+ + Cl- + Na+ + OH-=NH4OH(осадок) + Na+ + Cl-
NH4+ OH-=NH4OH(осадок)
FeCl3+3KOH=Fe(OH)3(осадок)+3KCl
Fe3+ + 3Cl- +3K+ + 3OH- =Fe(OH)3(осадок)+ 3K+ + 3Cl-
Fe3+ + 3OH- =Fe(OH)3(осадок)
