WebAnswers. The more negative the electrode potential greater is the reducing power of the electrode .The highest oxidation state of Cr +6 therefore it an lose 3 more electrons, whereas Fe need to lose only 1 electron to achieve it's highest oxidation state is +3 then Cr+3 is more reducing than Fe+2. 1 Crore+ students have signed up on EduRev. WebFeb 28, 2024 · The oxidised ion must have a stable electronic configuration to be a stronger reducing agent. Oxidation process involves the loss of electrons. Complete step by step …
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

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 ... WebNov 3, 2024 · With the same d-orbital configuration (da) C^2+ is a reducing agent while Mn^3+ is an oxidizing agent? asked Nov 4, 2024 in Chemistry by Tannu ( 53.3k points) the d- and f- block elements rosthern houses for sale
