Fe2 Ids - Top Viral
I would like to know the differences between Fe3+ and Fe2+ ions. I'm guessing they must differ in reactivity but I'm not sure how. Also, is there a way that we can observed the differences Electronic configuration for Fe2+ is [Ar]3d6 4s0 Electronic configuration of Cr2+ is [Ar]3d4 4s0 Cr2+ is a stronger reducing agent that Fe2+ in aqueous solution (d3 configuration more stabls than d5 in aqueous solution).
Understanding the Context
So Cr2+ has higher tendency on losing electron compared to Fe2+ so Fe2+ is more stable than Cr2+. inorganic chemistry - Stability order of Cr2+ ,Mn2+ , Fe2+ ,Co2 ... 9 I am struggling to rationalise why there are two infrared vibrational frequencies ($\pu {2082 cm^-1}$ and $\pu {2019 cm^-1}$) for the stretching of the terminal $\ce {CO}$ ligands of $\ce {Fe2 (CO)9}$. From my understanding of the structure, all six terminal $\ce {CO}$ ligands are equivalent and thus I would expect only one vibrational frequency.

Reaction of Fe2+ and S2- to form FeS Ask Question Asked 6 years, 2 months ago Modified 6 years, 2 months ago Reaction of Fe2+ and S2- to form FeS - Chemistry Stack Exchange Is this correct? What happens in the following equation then: $$\ce {2 FeCl3 (aq) + 3 Na2CO3 (aq) -> Fe2 (CO3)3 + 6 NaCl}$$ Will we get different end products? What will be solid? Hydroxides or oxides? Will there be carbon dioxide evolved?
