WebCr2+is a reducing agent because oxidation state of Chromium changes from Cr+2 to Cr+6in aqueous solution and Mn3+is an oxidizing agent because oxidation state of … WebCr 2+ is reducing and Mn 3+ is oxidising. Reason Cr 2+ and Mn 3+ have d 4 configuration. A Both Assertion and Reason are correct and Reason is the correct …

Explain why Cr2+ is strongly reducing while Mn3+ is …

WebMay 7, 2024 · Reducing agents are typically electropositive elements such as hydrogen, lithium, sodium, iron, and aluminum, which lose electrons in redox reactions. Hydrides (compounds that contain hydrogen in the … WebCr2+ is strongly reducing in nature. It has a d4 configuration. While acting as a reducing agent, it gets oxidized to Cr3+ (electronic configuration, d3). This d3 configuration can be written as 3t2g configuration, which is a more stable configuration. In the case of Mn3+ (d4), it acts as an oxidizing agent and gets reduced to Mn2+ (d5). This has an exactly half … svetliclaw hotmail.com

Cr2+ and Mn3+ both have d4 configuration. Thusa)both are …

WebKMnO4 acts as an oxidising agent in acidic medium. The number of moles of KMnO4 that will be needed to react with one mole of sulphide ions in acidic solution is ... Mn3+ and Co3+ are oxidising agents in aqueous solution. (iv) Ti2+ and Cr2+ are reducing agents in aqueous solution. Solution: Option (i) is the answer. 18. When acidified K2Cr2O7 ... 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 + as its +2 oxidation state has a half-filled d-subshell. Now my questions are: Why can't the … 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. svetlana wrightson
