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)+CuSO4(aq) ----------> Cu(s)+FeSO4(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 500.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 104.mg.Calculate the original concentration of copper(II) sulfate in the sample. Round your answer to 3 significant digits. _______________g/L
The amount of I3 (aq) in a solution can be determined by titration with a solution containing a known concentration of S₂O3(aq) (thiosulfate ion). The determination is based on the net ionic equation 2 S₂O3(aq) + 13(aq) - S₂O²(aq) + 31¯(aq) Given that it requires 37.4 mL of 0.470 M Na₂S₂O3(aq) to titrate a 25.0 mL sample of 13 (aq), calculate the molarity of I3 (aq) in the solution.
