Inorganic and Applied Chemistry

As we have a basic solution we balance with 2 OH- on the right side of the reaction giving:

4Ag + 8CN- + O 2  4Ag(CN) 2 - + 4 OH-

Last step is to balance with water molecules such that the atoms match on both sides of the reaction arrow.

In the last case we balance with 2 H 2 O-molecules on the left side:

2H 2 O + 4Ag + 8CN- + O 2  4Ag(CN) 2 - + 4 OH-

As an extra control one may control that the charges match on both sides of the reaction arrow:

Left side: 8 · (-1) = -8

Right side: 4 · (-1) + 4 · (-1) = -8

As an extra-extra control one may make sure that there are equally many of each type of atoms on both

sides of the reaction arrow:

Left side: 4 Ag, 8 C, 4 O, 8 N, 4 H

Right side: 4 Ag, 8 C, 4 O, 8 N, 4 H
