rinsed out with water, clean the insides with the test tube brush, and then perform a final rinse with
distilled water.
Part C
Follow these steps to complete the table:
1. Reuse the same test tubes from part B, labeled Fe2* and Fe*. Be sure they're clean.
2. Add 4 milliliters of iron(Il) sulfate to the test tube labeled Fe2*.
3. Add 4 milliliters of iron(II) nitrate to the test tube labeled Fe3+.
4. Add 4 milliliters of potassium permanganate to each test tube.
5. Observe the contents of the test tubes for about 10 minutes. Record your observations, noting any
evidence of a chemical reaction. If there is no evidence of a reaction, write "no reaction."
