Question

write the chemical equation for the reaction of thiosulphate ion and alkaline potassium permanganate.​

Answer 1

Explanation:

8 KMnO4 (aq) + H2O (l) + 3 Na2S2O3 (aq) → 8 MnO2 (s) + 3 Na2SO4 (aq) + 3 K2SO4 (aq) + 2 KOH (aq)

This is an oxidation-reduction (redox) reaction:

8 MnVII + 24 e- → 8 MnIV

(reduction)

6 SII - 24 e- → 6 SVI
