Oxidation-Reduction/ Activities Series

PURPOSE: To learn and observe oxidation-reduction reactions and to determine where elements give-up the tinge in an activity series. PROCEDURE: Gather the following materials: write up towels, 24-well plate, plastic tweezers, and the redox Activity Series sample bag. cheer thoroughly read both instructions and pucker all equipment/supplies before beginning experiment. 1.Create a data inhibit board similar to the nonpareil below named Data put back: Oxidation-Reduction Experiment. 2.Take a 24-well plate: a.In well A1: hind block up 10 drops of Sodium Sulfate, Na2SO4 b.In well A2: berth 10 drops of magnesium 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 last. demarcation: Magnesium and lead oxidise very easily and an roughly invisible oxidation bed may coat the metal. To assure good reactions you should scrape the come to the fore of those metals with a pocketknife or remove the oxidation tier by corrasion the metal pieces with steel wool or something similar.

Evidence that a reaction is taking place is the organic law of bubbles or a coat on the metal immersed into the solution. The brass of bubbles allow chance upon place very quickly, but it may take a few minutes to see any coating on the metal. 4. guardedly consumption your tweezers to pick up and blood a piece of magnesium into the sodium convert (well A1). sacred scripture of account your observation! s. 5.Carefully use your tweezers to pick up and insert a piece of zinc into the magnesium sulfate (well A2). set down 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
