Purpose: Oxidation States of Manganese To prepare solutions of manganese ions in different oxidation states. Materials: 5 test tubes ~25 mL KMnO$_4$ solution 100 mL beaker MnSO$_4$(s) (pinch) 4.0 M H$_2$SO$_4$ solution 2.0 M NaOH solution pipette 0.1 M EDTA solution NaHSO$_3$ solution 10 ml graduated cylinder Procedure: 1. Determine the oxidation number of Mn in each of the following compounds. Compound Oxidation # of Mn Colour Identifying Letter KMnO$_4$ +7 Purple E K$_2$MnO$_4$ +6 Green B MnO$_2$ +4 Brown A MnSO$_4$ +2 Colourless C MnCl$_2$ +3 Violet Rose D 2. Label 5 test tubes A, B, C, D and E. From your 100 mL beaker add 4 ml of the KMnO$_4$ to each test tube. 3. Set test tube E aside - do not add anything. It represents Mn in the 7+ state. 4. Add 1.5 mL of the H$_2$SO$_4$ to test tube A and add 2.0 mL of NaOH to test tube B. 5. Slowly add the NaHSO$_3$ solution to each test tubes of A, B and C (be particularly patient while adding to test tube B). Shake the test tube after each drop and observe any changes. If no changes occur add another drop. Record these observations. 6. To test tube D - add 5 ml of EDTA to one of the test tubes filled with KMnO$_4$. Add a pinch of MnSO$_4$. Observe and record any changes. 7. Compare the colours observed and fill in the observation table.
