Select true or false: the following net ionic equation correctly shows the result of this experiment: a piece of lead metal was added to an aqueous solution of copper(ii) nitrate, and within a few minutes it was observed that the lead turned black and crumbled. the characteristic blue solution of copper(ii) ions had faded. (note: lead forms a 2+ ion when it reacts.) pb(s) + cu2+(aq) → pb2+(aq) + cu(s)
