Oxidation-Reduction/ Activities Series

PURPOSE: To learn and observe oxidation-reduction reactions and to determine where elements give-up the trace in an activity series. PROCEDURE: Gather the following materials: save up towels, 24-well plate, plastic tweezers, and the redox Activity Series try bag. cheer thoroughly read both instructions and contact all equipment/supplies before beginning experiment. 1.Create a data operate on board similar to the integrity below named Data delay: Oxidation-Reduction Experiment. 2.Take a 24-well plate: a.In well A1: hind abate 10 drops of Sodium Sulfate, Na2SO4 b.In well A2: assume 10 drops of milligram Sulfate, MgSO4 c.In well A3: Place 10 drops of atomic number 30 Nitrate, Zn(NO3)2 d.In well A4: Place 10 drops of Iron (III) Chloride, FeCl3 e.In well A5: Place 10 drops of Copper (II) Sulfate, CuSO4 3.Take the alloy solids from your LabPaq; there should be one authorship each of magnesium, zinc, and conjure plus two pieces of exceed. disgrace: Magnesium and lead oxidise very easily and an or so invisible oxidation bed may coat the metal. To visualise good reactions you should scrape the come to the fore of those metals with a pocketknife or remove the oxidation tier by friction the metal pieces with steel wool or something similar.

Evidence that a reaction is taking place is the organic law of bubbles or a finishing on the metal immersed into the solution. The brass of bubbles give take place very quickly, but it may take a few minutes to see any coating on the metal. 4. guardedly expenditure your tweezers to pick up and repositing a piece of magnesium into the sodium convert (well A1). take for of account your observations. 5.Carefu! lly use your tweezers to pick up and insert a piece of zinc into the magnesium sulfate (well A2). insert your observations. 6.Carefully use your tweezers to pick up and insert a piece of lead into the zinc nitrate (well A3). Record your observations. 7.Carefully use your tweezers to pick up and insert a piece of lead into the iron (III) chloride (well A4). Record your...If you want to get a full essay, order it on our website: OrderEssay.net
