Calculate the value of the [Fe3+]/[Fe2+] if 3 cm3 of the 0.05 M Fe3+ solution is added to 25 cm3 of the 0.05 M Fe2+ solution

Answer 1

Is this before or after the disproportionation.
Before:
(Fe^3+) =- 0.05 x 3/28 = ?
(Fe^2+) = 0.05 x 25/28 = ?
or more simply, it is
[(0.05 x 3/25)/(0.05 x 25/28)] or just 3/25 = ?
