III ) Fe+3(aq) + SCN-(aq) ß→ Fe(SCN)+2(aq)

(3) Prepare a stock solution by mixing 2mL each of 0.1M FeCl3 and 0.1M KSCN in 100mL graduated cylinder. Add enough water to make 100mL solution. Note the color. If you are the first one to use this station, make this solution and save it for the rest of the class. If you are using someone else's stock solution, make sure to make observations of each reactant.

(4) *Add about 1mL of 0.1M FeCl3 to about 5mL of stock solution.

(5) *Add about 1mL of 0.1M KSCN to about 5mL of stock solution.

^^^What is the stress and which direction should the equilibrium shift

(6) *Add 0.1M AgNO3 DROPWISE (less than 1mL) to about 5mL of stock solution until almost all the color is discharges. (The white ppt is a mixture of AgCl and AgSCN.) Split the solution into two test tubes including the precipitate.

(6a) Add 0.1M KSCN dropwise (about 2mL) to one tube

(6b) Add 0.1M FeCl3 dropwise (about 2mL) to the other tube.

(Q4) Write a balanced net ionic equation showing what happened in step (6).

    My question is #2 for the reaction Fe3+ (aq) + SCN- (aq) FeSCN2+ (aq). The goal is to predict the color change (darker or lighter) for test tubes 2-8. I have attached the supplemental sheets given to help with the problem. The test tubes 2-8 are being manipulated either by temperature or things being added which can be seen by one of the pictures. 2. For reaction "UCTIONS are increased by the same amount.

    Not washing the precipitate in part III-2 that is used in part III-3 will have no effect on the identification of iron and manganese. True False When adding NaOH to the supernatent in part III-2, if a pH of only 7 was reached instead of 8, it would potentially give a false negative for iron and manganese.
