Dilute solution to a total of 4 mL with distilled water and divide the solution into 2 parts to be tested for Fe3+ ions in step 9 and Mn2+ ions in step 10. Add 1-2 drops 0.5M KSCN to one test tube from part 6. A blood red solution indicates the presence of Fe3+ ions. To the other half of the solution from step 6, add ~ 1mL 6M HNO3 and mix. ................
