Part B
Follow these steps to complete the table:
1. Reuse the same test tubes from part A, labeled Fe²+ and Fe³+. Be sure they're clean.
2. Add 4 milliliters of iron(II) sulfate to the test tube labeled Fe²+,
3. Add 4 milliliters of iron(III) nitrate to the test tube labeled Fe³+.
4. Add 4 milliliters of potassium iodide to each test tube.
5. Add 1 milliliter of the prepared starch solution to each test-tube.
6. Record your observations, noting any evidence of a chemical reaction. If there is no evidence of a
reaction, write "no reaction."
