the KI or Nass:Os is yellow, it has been contaminated and the solution must be completely discarded Notify your instructor immediately!!! A. Determination of the Orders of Reaction and the Rate 1.) Use small beakers he Rate Constant or graduated cylinders to obtain the volumes listed Pipette Compound 0.200M KNO 0.100M (NH4) S:O 0.100M (NH4) SO 0.200M KI 0.00500M NazS O Starch Volume (mL) per pair of students 15 100 25 100 75 10 5.00 mL 5.00 mL, 10.00 mL 5.00 mL 5.00 mL, 10.00 mL 5.00 mL Disposable dropper taining the following: Rxn Flask 2 Flask 3 10.00mL 0.200M KI10.00mL 0.100M (NHa).S:0 0.100M (NHS,O 5.00mL.0.00500M Na:S:O 10 drops starch solution Pour the solution from flask 1 into flask 3. Immediately pour th reaction inmedtour the contents of flask 2 into flask 3 as well and begin to swirl. Start timing the reaction immediately Swirl the flask during the entire reaction. At the first sign of a blue color: record the time measure and record the temperature inside the flask (to 1 decimal place). discard the reaction mixture in the waste bottle, located in the fume h e waste bottle, located in the fume hood. Make sure that all nasks are rinsed thoroughly before being used for the next reaction. 3.) Prepare three LABELED 125 mL Erlenmeyer flasks containing the following: Rxn Flask 2 Flask 3 5.00mL. 0.20OM KI 10.00mL 0.100M (NH.)>S:Os 5.00mL. 0.00500M Na S:O, 5.00mL 0.200M KNO 10 drops starch solution Pour the solution from flask 1 into flask 3.
