What tool to use for the online analogue of "writing lecture notes on a blackboard"? In what way are isotopes of a given element always different? The chemical formula is NaCl because we require one sodium ion for every chloride ion in order to balance the charges. For a precipitation reaction, the net ionic equation always shows the two ions that come together to form the precipitate. 1. Cupric chloride. 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). net ionic equation.
