To set up for this lab experiment, wear the appropriate personal protective equipment, including a lab coat, chemical splash goggles, and gloves
-
Prepare 250 mL of a 0.5 M aqueous solution of iron (III) nitrate. Measure out 50.5 g of iron nitrate nonahydrate on a top-loading balance. Place a powder funnel in the mouth of a 250-mL Erlenmeyer flask and pour the iron (III) nitrate nonahydrate into it.
-
Measure out 175 mL of deionized water with a graduated cylinder and pour it into the flask.
-
Remove the funnel, place a stir bar in the flask, and start stirring the mixture on a stir plate. While the mixture stirs, label a 250-mL polyethylene bottle as ‘0.5 M Fe(NO3)3’.
-
Once the solution appears homogeneous, place the funnel back in the flask and add another 75 mL of deionized water.
-
Continue stirring until the solution appears homogeneous again. Then, turn off the stir motor and remove the stir bar from the flask.
-
Transfer the solution into the polyethylene bottle. Store the capped bottle at the back of the instructor's hood until just before the lab.
-
Lastly, wash your glassware and equipment and put away the iron (III) nitrate nonahydrate.
