12/10/2020Task: Comparing Reactivities of Elements;1/7TaskComparing Reactivities of ElementsIn this task, you will rank several elements according to their reactivities. You’ll base yourrankings on whether a chemical reaction occurs between certain elements. Before you begin,read this information about lab safety .Estimated time to complete: 2 hoursIf you’ve purchased an Edmentum lab kit, remove the items that appear in the followingequipment list. The chemicals are located inside a box within the kit. You’ll also need a pen tolabel the test tubes.You’ll need these materials:test tube racktest tubes (quantity: 6)test tube labelsgraduated cylinderwash bottle with distilled water (Tap water is acceptable, but it can skew theexperimental results.)pipettes (quantity: 2)forceps50-milliliter Erlenmeyer ±askscooptest tube brushaprongogglesglovespen or ²ne-tip markersmall piece of sandpaperchemicals from Edmentum Lab kit:copper metal strip (quantity: 1)iron nails (quantity: 2)zinc metal strips (quantity: 3)copper(II) sulfate solution (10 milliliters)iron(III) nitrate solution (10 milliliters), also called ferric nitratemagnesium sulfate solution (10 milliliters)hydrochloric acid (30 milliliters)

Click the ProductResources tab followed by Datasheet.Always work safely:Do not work directly on a granite or marble countertop. These surfaces may bedamaged by hydrochloric acid.Keep lids on the chemical bottles at all times, except when you are actively dispensingfrom a bottle.Wear an apron, goggles, and gloves anytime you are working with chemicals, includingduring disposal.
