Balancing of Ionic Equations :
In these equations, charge balancing of atoms on both sides of the equation, e.g.,
Initial Cu2+(aq.) + H2S → CuS (s) + H+ (aq)
Balanced Cu2+ (aq.) + H2S → CuS (s) + 2H+ (aq)
We have balanced the charges. It was + 2 on LHS and we have made + 2 on RHS. Number of Hydrogen atoms, Cu and Sulphur atoms are also balanced on both sides.
