Lab: Types of Chemical Reactions Date: Lab Group Members: Safety Precautions: Wear safety goggles and gloves at all times. 6 M HCl and 6 M NaOH solutions are corrosive. If you spill any on your skin, immediately flush with water and notify your instructor. Procedure: 1. Perform each reaction according to the directions and record your observations. 2. If you see no immediate evidence of reaction, set the test tube aside for 10 minutes then re-examine. 3. Complete the balanced chemical equation for each reaction that occurs. If there is no evidence of reaction, write the words “no reaction” to the right of the arrow. (Use Activity Series or Solubility Table to complete single or double replacement reactions) Chemical Reactants and Products 1. Place ½ inch of magnesium ribbon in a test tube. Add 10 drops of 6 M HCl and observe. Mg (s) + HCl (aq) → 2. Place a piece of calcium metal in a test tube. Add 25 drops of distilled water and observe Ca (s) + H2O (l) → 3. Put 10 drops of copper II nitrate in test tube. Add 10 drops of sodium carbonate to the same test tube and observe. Cu(NO3)2 (aq) + Na2CO3 (l) → 4. Place a piece of zinc metal in a test tube. Add 10 drops of 6M HCl and observe. Zn (s) + HCl (aq) → Evidence of Reaction Type of Reaction Chemical Reactants and Products 5. Add 25 drops of hydrogen peroxide in a test tube. Add a pinch of *manganese IV oxide. Quickly light a wooden splint, blow it out, and stick the glowing end into the test tube (observe). H2O2 (aq) → 6. Put a pinch of copper II carbonate into a test tube. Add 10 drops of 6 M HCl and observe. CuCO3 (s) + HCl (aq) → 7. Place a piece of aluminum metal into a test tube. Add 10 drops of copper II chloride and observe. CuCl2 (aq) + Al (s) → 8. Hold a 6 cm piece of magnesium ribbon with a pair of tongs, bring over Bunsen burner flame and observe. Mg (s) + O2 (g) → 9. Place a piece of copper metal into a test tube. Add 10 drops of 6 M HCl and observe. Cu (s) + HCl (aq) → 10. Add 10 drops of 6 M HCl to a test tube. Slowly add the same amount of 6 M NaOH, 1 drop at a time and observe. HCl (aq) + NaOH (aq) → Evidence of Reaction *MnO2 is a catalyst. It is not consumed in the reaction. Type of Reaction
