ZnCl2 + 2NaOH = Zn(OH)2 + 2NaCl
 Zn^{2+} + 2Cl^{-} + 2 Na^{+} + 2 OH^{-} = Zn(OH)_{2} + 2 Na^{+}+ 2Cl^{-}
Zn^{2+} +2 OH^{-} = Zn(OH)_{2}
Zn(OH)2 + 2HCl = ZnCl2 + 2H2O
Zn^{2+}+2OH^{-} + 2H^{+} +2Cl^{-} = Zn^{2+} + 2Cl^{-} +2H_{2}O
2H^{+} + 2OH^{-} = 2H_{2}O
Zn(OH)2 + 2NaOH = Na2ZnO2 + 2H2O
2H^{+} + ZnO_{2}^{2-} +2Na^{+}  +2OH^{-} = 2Na^{+} + ZnO_{2}^{2-} +2H_{2}O
2H^{+} + 2OH^{-} = 2H_{2}O
