Answer» SOLUTION :1. in transitionseriesas wemovedownfrom Tito Znthe standardreductionpotential `E_(m^(2+))^(0)` valueis approaoachingtowardslessnegativevalueand copperhasa positive . 2.`E_(m^(2+)//M)^(0) ` value formangancesand zincare morenagativethen regulartrend.it isdue to`d^(10)` configurationin `ZN^(2+)` 3. Thehighreductionpotentialof `Mn^(3+) // Mn^(2+)` indicates`Mn^(2+)` is morestablethan`Mn^(3+)` 4.Thehighreductionpotentialof `Mn^(3+)` indicates`Mn^(2+)` morestablethen `Mn^(3+)` 5 `Mn^(3+)` has a`3d^(4)` configurationwhilethatof `Mn^(2+)` is `3d^(5)` the extrastabilityassociated witha HALF filledd sub-shellmakesreducationof `Mn^(3+)` veryfeasible`[E^(0) =+1.51V]` |
