Solving for a reactant in solution
One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(II) carbonate, in concentrated sulfuric acid.
The sulfuric acid reacts with the copper(II) carbonate to produce a blue solution of copper(II) sulfate. Scrap iron is then added to this solution, and pure copper
metal precipitates out because of the following chemical reaction:
Fe(s) + CUSO,(aq)
Cu(s) + FESO,(aq)
Suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. He adds powdered iron to a 250. mL
copper(II) sulfate sample from the plant until no more copper will precipitate. He then washes, dries, and weighs the precipitate, and finds that it has a mass of
134. mg.
Calculate the original concentration of copper(II) sulfate in the sample. Be sure your answer has the correct number of significant digits.
