Which of the following products is formed by the reaction of manganese (II) ion salt with peroxodisulphate (S2O2−8)?
Peroxodisulphate salts (e.g., Na2S2O8) are strong oxidizing agents used asbleaching agents for fats, oils, etc.
Given :
O2(g)+4H⊕(aq)+4e−→2H2O(l)
E⊖=1.23V
S2O2−8(aq)+2e−→SO2−4(aq)
E⊖=2.01V
