Cr2 is strong reducing agent

WebOct 9, 2024 · Cr2+ is a stronger reducing agent that Fe2+ in aqueous solution (d3 configuration more stabls than d5 in aqueous solution). So Cr2+ has higher tendency on losing electron compared to Fe2+ so Fe2+ is more stable than Cr2+. Mn2+ has most stable and Co2+ is least stable (least exchange energy due to only 3 unpaired electrons). Share.

WebEasy solution is given here.If you have any queries , please comment down below.Keep learningKeep growing. 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 ... slow horses 2 stagione streaming https://drogueriaelexito.com
