SUMMARY
The equivalence factor of the compound FeSO4.Cr2(SO4)3.24H2O is determined to be 8, based on the precipitation of hydroxides from both iron and chromium. However, a redox reaction analysis suggests an equivalence factor of 7, as two chromium ions (Cr(III)) oxidize to chromium (Cr(VI)), releasing 6 electrons, while one iron ion (Fe(II)) oxidizes to iron (Fe(III)), releasing 1 electron. This discrepancy highlights the complexity of calculating equivalence factors in compounds with multiple reactive components.
