When hypo solution is added to KMnO4 solution, then:
Na2S2O3 is converted to Na2S4O6
Na2S2O3 is converted to Na2SO4.
KMnO4 is converted to K2MnO4
KMnO4 is converted to MnSO4
KMnO4 is a strong oxidizing agent, hence it changes the oxidation state of S to maximum possible oxidation state.
In weak alkaline medium KMnO4 converted in to?
