A mixture contains only CuCl 2 and FeCl 3 . A 0.7391 g sample of the mixture
Question:
A mixture contains only CuCl2 and FeCl3. A 0.7391 g sample of the mixture is completely dissolved in water and then treated with AgNO3(aq). The following reactions occur.
CuCl2(aq) + 2 AgNO3(aq) → 2 AgCl(s) + Cu(NO3)2(aq)
FeCl3(aq) + 3 AgNO3(aq) → 3 AgCl(s) + Fe(NO3)3(aq)
If it takes 86.91 mL of 0.1463 M AgNO3 solution to precipitate all the chloride as AgCl, then what is the percentage by mass of copper in the mixture?
