A chemist mixes 200.0mL of 0.800 M Fe(NO3)3 and 300.0 mL of 0.750 M K2Cr04 and enough of either 0.400 M KOH or 0.400 M Pb(no3)2 to end up with only two spectator ions in solution.
a. How much precipitate will be formed
b. How many mL of KOH or Pb(No3)2 must be used
c. What are the concentrations of spectator ions in solution
