In the net ionic equations, we are not include the spectator ions in the equations. 1) The chemical reaction betweenaqueous solutions of copper(II) chloride and potassium carbonate can be given as- Molecular equation : Here all the reactants and products are formed in their molecular form as- CuCl2 (aq) + 2KNO3 (aq) ---------->Cu(. The final piece of the puzzle is the electrochemical reaction consuming the created H+ (moving the above equilibrium to the right) activated by the oxygen in air in the presence of cuprous: 4 Cu+ + O2 (from air) + 2 H+ 4 Cu2+ + 2 OH- (source: Wikipedia reference above and also Eq (7) below). Spectator ions are those that appear on both sides of the equation as ions. I explain my presumed formation of what I surmise is copper oxychloride as a result of a comproportionation reaction from the action of copper metal acting on cupric chloride (see https://en.wikipedia.org/wiki/Copper(I)_chloride ) in the presence of a high chloride concentration creating a soluble CuCl2- complex: Cu(ll)L + Cu <--> 2 Cu(l)L (L here refers to a chloride ligand).
