The equivalent weight of MnO_(4)^(-) ion in acidic medium is

0.1 " mol of " MnO_(4)^(ɵ) (in acidic medium) can:

Assertion :- Equivalent weight of KMnO_(4) in acidic medium is M//5 (M=molecular weight) while in basic medium, it is equal of M/3. Reason :- In acidic medium, 1 mol of MnO_(4)^(-) gains 5 mole electrons while in basic medium it gains 3 mole electrons.

Assertion : In acid solution, permanganate is reduced to Mn^(2+) by an excess of reducing agent. Reason : MnO_(4)^(-) reduced in Mn^(2+) in acidic medium and the product in the presence of an excess of permanganate is MnO_(2) .

150 ml (M)/(10) Ba(MnO_(4))_(2) in acidic medium can oxidise completely

100 " mL of " (M)/(10) Ca(MnO_(4))_(2) in acidic medium can be oxidised completely with

1 mole of ferric oxalate is oxidised by x mole of MnO_(4)^(-) in acidic medium, Hence value of x is:
