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. WebIdentify the incorrect statement. (1) The oxidation states of chromium in CrO 4 2– and Cr 2 O 7 2– are not the same (2) Cr 2+ (d 4) is a stronger reducing agent than Fe 2+ (d 6) in water. (3) The transition metals and their compounds are known for their catalytic activity due to their ability to adopt multiple oxidation states and to form complexes.
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 … 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+.
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. WebIf the standard electrode potential (E 0) of metal is large and negative, the metal is a powerful reducing agent Cr A 2 + + 2 e A − Cr Fe A 2 + + 2 e A − Fe E 0 = – 0.91 V E 0 …
