1 L `(M)/(10) Ba(MnO_(4))_(2)` in acidic medium can be oxidised completely with `(1)/(6)` L of x M ferric oxalate. The volume of x is

Answer

1

Explanation

(a) `10e^(-) +2MnO_(4)^(-) rarr 2Mn^(2+) (n = 5)`
`{:(Eq of MnO_(4)^(-) -=, Eq of Fe_(2) (C_(2)O_(4))_(3)),((n=5),(n=6).):} `
`1L xx (M)/(10) xx 10 -= (1)/(6) L xx 6 xx x x = 1M`
