Purpose - Chemical Reactions II Lab16 Date: Chemical Reactions II Purpose - Observe and classify different types of chemical reactions

Part 1 – Iron in aqueous copper (II) sulfate Experiment - Part 1 – Iron in aqueous copper (II) sulfate Place an iron nail in a beaker containing approx. 40 mL of copper(II) sulfate solution. Record observations after a few minutes. Return nail & solution back to original place

Part 2 – Copper in aqueous iron (III) sulfate Place a copper wire in a beaker containing approx. 40 mL of iron (III) sulfate solution. Record observations after a few minutes. Return wire & solution back to original place

Chemical well plate Part 3 – Chlorides with Sulfates 10 drops 10 drops 10 drops SrCl2 CaCl2 BaCl2 10 drops Na2SO4 10 drops K2SO4 Chemical well plate

Well Plate Observations SrCl2 CaCl2 BaCl2 Na2SO4 K2SO4

2. Add drops of Na2SO4 to each test tube Part 3 – Alkaline Earth Chlorides + Sodium Sulfate record observations Pipet 10.0 mL of MgCl2, CaCl2 & BaCl2 into 3 separate test tubes. Add drops of Na2SO4 to each MgCl2 is soluble, try SrCl2 1. pipet 10 mL MgCl2 10 mL CaCl2 10 mL BaCl2 2. Add drops of Na2SO4 to each test tube

Analysis – Write a skeleton equation for part 1. Assume iron(III) ions were produced. What was observed in part 2? Explain. Write a skeleton equation for all 6 equations in part 3. What was observed in part 3? Explain. Balance the equations in #1 & #3 Classify equations 1 and 3 into one of the five reaction types we have discussed. Write a balanced chemical equations for strontium chloride reacting with manganese (II) sulfate. Results – This is the space for YOUR statement that DESCRIBES what the different types of chemical reactions are AND what types of reactions you observed in Lab #15 & Lab #16
