blue. The reaction produces a reddish brown color copper metal and clear aluminum nitrate solution. Beaker Before Reaction Beaker After Reaction Blue colored solution Clear solution Silver piece of Al Small silver piece of Al Dark reddish brown solid According to the following data, what is the limiting reactant? Copper Nitrate solution, because the solution was blue at the end of the reaction showing some copper nitrate remained at the end of the reaction. Aluminum, because some Aluminum remained at the end of the reaction. Aluminum, because it was completely consumed in the reaction. Copper nitrate solution, because the solution was clear at the end showing it was completely consumed in the reaction.
