Equilibrium Lab

• Lab posted in Schoology
• Prep and conduct lab Friday in class
• One class group for this experiment

Notes

• HNO3 is stored in concentrated solution: 15.8 M
• Start by making 2.00 liters of .50 M HNO3 (31.65 mL of concentrated solution in 1.00 liters of final solution
• Split the 0.500 M HNO3 solutions into 4 parts. Each part will have a different “flavor” (0.0020 M Fe(NO3)3, 0.20 M Fe(NO3)3, 0.0020 M KSCN, plain 0.50 M HNO3)
• Do not make the solutions that combine acid and each of the solutes unless you will use them during the class period.
• You will need to create a calibration curve to use in the lab.

Homework

• write a full lab report in your LNB to be turned in Wednesday, March 4th
