5 HSCN + 6 KMnO4 + 4 H2SO4 → 6 MnSO4 + 3 K2SO4 + 5 HCN + 4 H2O
This is an oxidation-reduction (redox) reaction:
6 MnVII + 30 e- → 6 MnII (reduction)
5 S-II - 40 e- → 5 SVI (oxidation)
5 CIV + 10 e- → 5 CII (reduction)
KMnO4 is an oxidizing agent, HSCN is a reducing agent, HSCN is an oxidizing agent.
