Re: Iron (III) Oxide + Sodium Sulfate = ??

Oh, also Fe(NO3)3 + K2CrO4 = ?

Thanks a bunch.

UPDATE: I got the first one 2Fe(NO3)3 + 3Na2S = Fe2S3 + 6NaNO3.
I still have no idea with the Potassium Chromate. Please help!
If Fe2(CrO4)3 is not well soluble:

Code: Select all

2 Fe(NO3)3 + 3 K2CrO4 = Fe2(CrO4)3 + 6 KNO3
