  1. Introduction to Equilibrium:Fe3+ + SCN- Fe(SCN)2+clear clear red-orange • Put equal amounts of 0.002M KSCN and 0.002M Fe(NO3)3 into all 4 wells • Record what you see • What substances are in the wells? • Add about 6 drops of 0.20M Fe(NO3)3 into well #2 • Record what you see • Does the result change your answer to 1b? • Add 1 grain of KSCN to well #3 and 4 • Record what you see • Does the result change your answer to 1b? • Add 6 drops of 0.1M Na3PO4 (which makes a precipitate with the iron III) to well #4 • Record what you see • Does the result change your answer to 1b? • Finally, this is an equilibrium reaction. Define “equilibrium” in your own words Reference + Fe3+ + SCN- - Fe3+
