Answer #1

KMnO4 is an oxidiing reagent which can be used for various purpose.

1) It is used to eliminate iron and H2S from well water

2) The main use of KMnO4 is as a reagent for the synthesis of organic compounds

Alkene can be converted into 1,2 diols in mild condition  

Alkene can be cleaved to carboxylic acids in acid condition

Benzylic positions can be oxidized to carboxylic acid

3) In inorganic chemistry it can be used to determine the total oxidisable organic material in an aqueous sample

Further it can be used as Fruit preservation, In Survival kits.

KMnO4 is used as the titrant in a potentiometric titration of tin(II) to tin(IV), using a S.C.E. reference electrode. Calculate the cell potential in a pH =3.00 buffer solution at the equivalence point. ½ Hg2Cl2(s) + e = Hg(l) + Cl-(aq)                        E(saturated KCl) = 0.241V Sn4+ + 2e → Sn2+ (analyte)                                E° = 0.139V MnO4- (titrant) + 8H+ + 5e → Mn2+ + 4H2O          E0 = 1.507V
