Equivalence factor of the salt is FeSO4.Cr2(SO4)3.24H2O is
Ans is 8.
The Attempt at a Solution
Equivalence factor of an acid or base is its basicity or acidity, and for a compound undergoing redox reaction, it is the number of electrons exchanged per mole of compound. I'm not sure how to go about in the case of the given salt.
