The nice orange-red colours are now a thing of the past.
A few helpful hints:
Carefully determine the initial concentrations of SCN- and Fe3+
The initial [Fe3+] for test tubes 2 to 5 requires the use of c1V1=c2V2 twice.
When the determination of Kc is done, the results may vary quite a bit.
Generally they are in the 100 to 300 range.
Complete the follow-up to this lab in a timely fashion. Sooner = better.
If you were absent for the lab - see me for some "results" that could be used to work through the various calculations.
