Cr2+ is a strong reducing agent than fe2+
Webb. Cr3+ For a redox reaction to occur the reducing agent must be below the oxidizing agent. This will result in a backslash (\) if they are connected with a line. So in this case we need a reducing agent that is below Cl2 and above … WebConsider the following cell reaction at 25C. 2Cr3+ (aq)+3Zn (s)3Zn2 (aq)+2Cr (s) Calculate the standard cell potential of this cell from the standard electrode potentials, and from this obtain G for the cell reaction. Use data in Appendix C to calculate H; note that Cr (H2O)63+ (aq) equals Cr3+ (aq). Use these values of H and G to obtain S for ...

WebJan 26, 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+. WebIn aqueous solution, C r 2 + is a stronger reducing agent than F e 2 +. This is because ... The oxide, which cannot act as a reducing agent, is: Hard. View solution > (i) In the …
WebIf we are reducing copper 2+ to solid copper, the standard reduction potential is +.34 volts. If we are reducing zinc 2+ to solid zinc, the standard reduction potential turns out to be -.76 volts. The more positive value, the more likely the substance is to be reduced, so obviously +.34 is more positive than -.76. WebIn aqueous solution, Cr 2+ is a stronger reducing agent than Fe 2+. This is because: A Cr 2+ ion is more stable than Fe 2+. B Cr 3+ ion with d 3 configuration has favourable …
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. WebThe 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.
