Predict the number of unpaired electrons and the magnetic properties of [Fe(C2O4)3]3- ion.
Added by Tommy M.
Step 1
The oxalate ion (C2O4)2- has a charge of -2. Since there are three of them, the total charge contributed by the oxalate ions is -6. The overall charge of the complex ion is -3, so the charge on the Fe must be +3 to balance out the charges. Show more…
