Cu(OH)2+ 2HCl-->CuCL2+2H2O

Cu²⁺+2OH⁻+2H⁺+2CL⁻-->Cu²⁺+2CL⁻+2H2O

2OH⁻+2H⁺-->2H2O

K2CO3+2HNO3-->2KNO3+H2O+CO2

2K⁺+CO²⁻₃+2H⁺+2NO²⁻₃-->2K⁺+2NO²⁻₃+H2O+CO2↑

CO²⁻₃+2H⁺-->H2O+CO2↑

Mn(OH)2+H2SO4-->MnSO4+2H2O

Mn²⁺+2OH⁺-->2H⁺+SO²⁻₄-->Mn²⁺+SO ²⁻₄+ 2H2O

2OH⁻+2H⁺-->2H2O

2LiOH+H2SO4-->Li2SO4+2H2O

2Li⁺+2OH⁻-->2H⁺+SO²⁻₄-->2Li⁺+SO²⁻₄+2H2O

2OH⁻+2H⁺-->2H2O
