Question 6
Wear eye protection and disposable gloves when handling solutions. Work under teacher supervision. Investigation 1: an iron nail is placed in about 200 cm³ of copper nitrate solution in a beaker on an electronic balance. The beaker is covered with a watch glass while it stands for a week; the watch glass is removed before the final weighing.
Pour about 200 cm³ of copper nitrate solution into a beaker. Place the beaker on an electronic balance and put an iron nail in it. Record the mass and write it on a strip of tape. Stick the tape to the beaker.
Total mass of reactants = ______
