Cr2 is strong reducing agent
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+. 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.

Did you know?
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 … WebGood reducing agents include the active metals, such as sodium, magnesium, aluminum, and zinc, which have relatively small ionization energies and low electro-negativities. …
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. 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 …
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+. WebWhich is the stronger reducing agent Cr2+ or Fe2+? Tamil Nadu Board of Secondary Education HSC Science Class 12th. Textbook Solutions 10946 ... the metal is a powerful …
WebAnswer: Cr2+ is a stronger reducing agent than Fe2+. ... Thus Cr2+ is easily oxidised to Cr3+ but Fe2+ cannot be as readily oxidised to Fe3+. How do you determine the best oxidizing agent? The higher the electronegativity the greater the pull an oxidizing agent has for electrons. The higher the pull for electrons the stronger the oxidizing agent.
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. electric start leaf blower gasWebIf 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. electric start lawn mower wiring diagramWebThere 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.
