Two solutions of `0.1M cr_(2) O_(7)^(2-)(aq.)` and `0.1M MnI_(4)^(-) (aq.)` are to be used to titatre (titrating solution) be required for a given solution of `fe^(2+)(aq.)`
(b) If a given titration requires `24.50 mL` of `0.100M Cr_(2)O_(7)^(2-) (aq.)`,how many `mL` of `0.100M MnO_(4)^(-) (aq.)` would have been required if it had been used instead?

Answer

(a) Vol. Of `MnO_(4)^(-)` required will be `1.2` times fo vol. of `Cr_(2)O_(7)^(2-)`, (b) `29.4mL`
