Question
What is the concentration of the FeSCN2+ in the stock solution?
In Part A a stock solution will be prepared by mixing solutions containing the colorless
thiocyanate ion. In preparing the stock solution, we will make the iron (III) ion conce
the thiocyanate ion concentration. This causes the equilibrium above to shift far to the
essentially all of the SCN into FeSCN²+. We will then assume that the equilibrium
equals the original concentration of the SCN.
30 mL of a stock FeSCN2+ solution will be prepared by mixing the following in a sm
measure volumes:
3.0 mL of 0.00200 M KSCN solution
10.0 mL of 0.200 M Fe(NO3)3 solution
17.0 mL of 0.5 M HNO3 solution
