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.
WebC r X 2 + gets converted to C r X 3 + as the +3 oxidation state has half-filled t 2 g orbitals; thus it is a good reducing agent. On the other hand M n X 3 + gets converted to M n X 2 … WebMeans, one which will have a greater tendency to lose e ⊖, would be better reducing agent. ∴ F e + 2 having 3 d 6 The configuration will be more reducing because after losing an electron it will have d 5 configuration which is stable as it is half-filled configuration.
WebThe following reactions are involved when Cr 2+ and Fe 2+ act as reducing agents. Cr 2+ Cr 3+ Fe 2+ Fe 3+ The value is - 0.41 V and is +0.77 V. This means that Cr 2+ can be easily oxidized to Cr 3+, but Fe 2+ does not get oxidized to Fe 3+ easily. Therefore, Cr 2+ is a better reducing agent that Fe 3+. WebC r X 2 + is a better reducing agent. As it attains a d 3 configuration on loosing an electron while F e X 2 + attains d 5 configuration. In an aqueous medium d 3 (half filled t X 2 g orbital) is more stable than d 5. Share …
WebCr 2+ is a stronger reducing agent than Fe 2+. This can be explained on the basis of the standard electrode potential values E° (Cr 3+ /Cr 2+ = –0.41 V) and E° (Fe 3+ /Fe 2+ = + 0.77 V). Thus Cr 2+ is easily oxidised to Cr 3+ but Fe 2+ cannot be as readily oxidised to Fe 3+. I hope this answer will help you. Thanks & Regards. Yash Chourasiya.
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 … fantastic fiction mary baloghWebCr 2+ is a strong reducing agent. Medium Solution Verified by Toppr Cr 2+ has a d 4 configuration while after reduction it gets converted to Cr 3+−d 3 configuration which has … fantastic fiction mary higgins clarkWebThe E0 Cr3+/Cr2+ and E0 Fe3+/Fe2+ values are −0.41 V and 0.77 V respectively. Hence, Cr2+ can easily oxidize to Cr3+, but Fe2+ does not get oxidized to Fe3+ easily. Therefore, Cr2+ is a better reducing agent that Fe3+. Final answer: Cr2+ is a stronger reducing agent. Suggest Corrections. 0. corningware slow cooker replacement knobWebReducing agent :- The tendency to loose electrons or to undergoes oxidation easily. → It based on the number of maximum electrons that it can given out. → We know for Cr +6 is maximum, So Cr +2 can lose 4e −. → But for Fe +3 is … corningware simplylite lidsWebAug 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+. corningware slow cooker insertWebThe 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 … fantastic fiction marion chesneyWebJun 26, 2014 · Cr 2+ is reducing agent as its configuration changes from d 4 to d 3, when it is oxidized to Cr 3+.The d 3 configuration have a half-filled t 2g level which is very stable. On the other hand, the reduction of Mn 3+ to Mn 2+ results in the half-filled (d 5) configuration which has extra stability hence Mn 3+ acts as oxidizing agent. fantastic fiction martin edwards
