Chemistry experiment

  1. 1. By Rob Sbaglia
  2. 2.  The aim was to find out whether I could use different metals affect a nail rusting.
  3. 3.  Zinc ribbon  Copper ribbon  Vaseline  4 iron nails  4 test tubes  test tube holder
  4. 4. 1. Wrap the copper ribbon around a nail as pictured on the left. 2. Wrap the zinc ribbon on another nail as shown. 3. Completely cover one of the nails with vaseline. 4. Into a fourth test tube place a nail. 5. Fill each tube with water and leave standing for 4 days
  5. 5. Nail Result Nail with copper Lots of rusting Nail with zinc No rusting Nail with vaseline No rusting Nail with water Lots of rusting
  6. 6.  It was hard to see how much rusting had happened. I think next time I might weigh the nails and see if they have changed weight.  Rusting happens when water comes into contact with iron. I read that some metals rust instead of iron if they are in there together. The rust preferred the zinc to the iron, but the rust preferred the iron to the zinc Copper doesn’t rust Zinc rusts instead of nail
  7. 7.  In conclusion, copper doesn’t rust so it is no good at protecting a nail. Zinc does rust, so it can protect a nail from rusting.
