The equivalent weight of potassium permanganate in neutral medium is given as `M/X` (M = molecular wt.). Then 'x' is

Equivalent weight of Potassiumpermaganate in strong alkaline medium is

The equivalent mass of KMnO_4 in alkaline and neutral mediums is ul"one-fifth" of its molecular mass.

Potassium permanganate is used as a ul"reducing agent" in acidic medium.

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.

Equivalent weight of MnO_(4)^(ɵ) in acidic neutral and basic media are in ratio of:

Equivalent weights of K_(2)Cr_(2)O_(7) in acidic medium is

STATEMENT - 1 : Equivalent weight of a substance can never be greater than its molecular weight. STATEMENT - 2 : Equivalent weight of boric acid is (M)/(1) where M is the molecular weight. STATEMENT - 3 : Equivalent weight of H_(3)PO_(2) is (M)/(3) .

Molecular weight of an organic acid is given by:

Equivalent weight of Mohr salt in the titration with KMnO_(4) is (M-Molecular weight)

Equivalent weight of H_(3) PO_(2) is ( M rarr molecular weight)
