Standardization of KMnO4 using Mohrs-salt.
Titration lab, watch the video for a quick review of the concepts.
- KMnO4 0.02 M. Dissolve 3.16 grams KMnO4 in 1 Liter distilled water
- FeSO4(NH4)2SO4.6H2O 0.1 M. Dissolve 3.92 grams in 100 mL of distilled water. Add 10 mL of 0.5 M H2SO4 before the solution is completely made up. This prevents hydrolysis of Fe2+
- 0.5 M H2SO4
