copper compounds such as copper (II) sulfate are toxic. before disposal, these compounds must be treated to reduce their toxicity. describe how to use steel wool to remove the Cu 2+ ions from an aqueous solution of copper (II) sulfate
Fe(s) + Cu^2+ ==> Fe^2+ + Cu(s)
Drop the steel wool into the copper solution and that's all there is to it.
Due to the fact that the iron in the steel wool chemically reacts with the aqueous solution, we can conclude that during the reaction the iron displaces the copper. When copper is displaced,we can then remove the separate the iron sulfate solution from the solid copper.
