Task 1Observing Oxidation-Reduction ReactionsIn this task, you will carry out several oxidation-reduction reactions to observe the patterns inwhich combinations of chemicals react or don’t react with each other. Before you begin this task,read these lab safety guidelines . To review how to use a graduated cylinder and an electronicbalance, watch these videos about measuring volume and measuring mass .Estimated time to complete:Total time: 24 hoursActive time: 1.5 hoursIf you’ve purchased an Edmentum lab kit, remove the items that appear in the equipment list.The chemicals are located inside a box within the kit. You’ll also need distilled or tap water and apen or ±ne-tip marker for labeling test tubes.You’ll need these materials:volumetric ²askelectronic balanceweighing boats (3)wash bottle with distilled water (tap water is acceptable but may skew experimental results)test tube racktest tubes (6)labeling tapesandpaperstirring rodforcepsaprongogglesglovespen or ±ne-tip markerchemicals from kit:zinc nitrate (about 8 grams)magnesium nitrate (about 7 grams)copper(II) nitrate (about 7 grams)zinc strips (2)copper strips (2)magnesium ribbon (40 centimeters)For more information about each chemical, view the safety data sheets .
