Which is stronger reducing agent Fe^2 + (or) Cr^2 + . Why?

WebAug 27, 2024 · Answer: Cr2+ is a stronger reducing agent than Fe2+. This can be explained on the basis of the standard electrode potential values E°(Cr3+/Cr2+ = –0.41 V) and E° (Fe3+/Fe2+ = + 0.77 V). Thus Cr2+ is easily oxidised to Cr3+ but Fe2+ cannot be as readily oxidised to Fe3+. WebAug 20, 2024 · Cr 2+ is strong reducing while Mn 3+ is strongly oxidising.. E 0 Cr 3+ /Cr 2+ is -0.41 V . Cr 2+ + 2e-→ Cr E° = – 0.91V.. If the standard electrode potential E° of a metal is large and negative, the metal is a powerful reducing agent because it loses electrons easily. story of la catrina https://blahblahcreative.com

WebThe question is the same as the title states. In my textbook, [NCERT Chemistry I for Class 12 , pg no 217.] the following is written $\ce{Cr^{2+}}$ gets converted to $\ce{Cr^{3+}}$ as the +3 oxidation state has half-filled $\mathrm{t_{2g}}$ orbitals; thus it is a good reducing agent. On the other hand $\ce{Mn^{3+}}$ gets converted to $\ce{Mn^{2+}}$ as its +2 … WebThere are two reasons for Cr2+ to be more reducing than Fe2+ : 1)The values of reduction potentials of Cr2+ and Fe2+ are -.91 and -.44 volts respectively. As we know that the more the reduction potential greater the reducing power of the electrode. 2)The highest oxidation state of Cr is 6+. And so the Cr2+ ion can easily loose 2 more electrons ...

WebCr2+ is strong reducing agent than Fe2+.Reason: d4 → d5 occurs in case of Cr2+ to Cr3+.But d6 → d5 occurs in case of Fe2+ to Fe3+. In a medium (like water) d3 is more stable as compared to d5. WebNov 3, 2024 · 1 Answer. Cr2+ has d4 configuration while Cr3+ has more stable d5 configuration. Thus, Cr has a tendency to acquire Cr3+ due to greater stability of +3 …

WebOct 9, 2024 · Cr2+ is a stronger reducing agent that Fe2+ in aqueous solution (d3 configuration more stabls than d5 in aqueous solution). So Cr2+ has higher tendency on losing electron compared to Fe2+ so Fe2+ is more stable than Cr2+. Mn2+ has most stable and Co2+ is least stable (least exchange energy due to only 3 unpaired electrons). Share.
