The known metal ion solution used contains 0.10 M of each of the six metal ions (i.e. 0.10 M Ag+ and 0.10M Pb2+). An equal volume of 3 M HCl and the known solution are mixed. What are the inital concentrations of Ag+, Pb2+, and Cl- before any precipitation/reaction occurs, but after the mixing (i.e. dilution)?
