Explanation of the solution to the problem: when drawing up complete and abbreviated ionic equations, gases insoluble in water, as well as slightly dissociated compounds, are not assigned to ions.
1. Molecular equation of interaction of cadmium chloride and barium hydroxide with the formation of water-insoluble cadmium hydroxide:
СdCl2 + Ba (OH) 2 => BaCl2 + Cd (OH) 2 (precipitate).
2. Complete ionic equation:
Cd (+2) + 2Cl (-) + Ba (2+) + 2OH (-) => Ba (2+) + 2Cl (-) + Cd (OH) 2 (precipitate).
3. Abbreviated ionic equation:
Cd (+2) + 2OH (-) => Cd (OH) 2.
