Cr2 is strong reducing agent
WebJan 21, 2012 · why Cr2+ is a better reducing agent than Fe2+ when Cr2+ has electronic configuration 3d4 i.e can easily gain one electron to have stable 3d5 electrnic configuration and hence should be a good oxidising agent. ... 21 Jan, 2012, 08:17: PM Expert Answer Cr 2+ is a stronger reducing agent because it can lose one of its electron to become Cr … 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 …
Cr2 is strong reducing agent
Did you know?
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 ...
WebReducing 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 … 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.
WebSolution. Cr 2+ is strong reducing while Mn 3+ is strongly oxidising. E Cr Cr E Cr 3 + / Cr 2 + 0 is −0.41 V. Cr A 2 + + 2 e A − Cr. E 0 = – 0.91 V. If the standard electrode potential E 0 of metal is large and negative, the metal is a powerful reducing agent because it loses electrons easily. Mn Mn A 3 + + 3 e A −. WebCr 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 …
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.
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. compare the market driving lessonsWebC 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 … ebay rift magnetic gunstockWebJun 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. comparethemarket electricWebFeb 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 … ebay rifle sightsWebMeans, 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. ebay rifle scopes usedWebANSWERS (SALT ANALYSIS) EXERCISE–I Q.1 A MgCl2 , B Mg (NH 4 )PO4 .6H 2O , C Mg 2 P2O7 , D NH 3 Q.2 X is NH 4Cl Q.3 ZnCl2 2 AgNO3 2AgCl Zn(NO3 )2 (X) White ZnCl2 2NaOH Zn(OH )2 2 NaCl White Zn (OH )2 2 NaOH Na 2 ZnO 2 2 H 2O Colourless soln Na2 ZnO2 H2 S ZnS 2 NaOH White Q.4 (1) Since (A) gives chromyl chloride test … compare the market drone insuranceWebCr 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. ebay rifton youth shoiwer chair base
