Why is ferric ion more stable than ferrous ion?
Fe3+ is more stable than Fe2+. This is explained with the help of the electronic configuration. In Fe3+ ions, there are five 3d half-filled orbitals and is more symmetrical than Fe2+. Whereas in Fe2+ ion there are four 3d half-filled orbitals and one orbital is filled.
Which is more stable Fe2+ or Fe3+ and why?
Among Fe3+ and Fe2+ , Fe3+ is more stable due to half filled d-orbital. This can be explained by Aufbau principle. Half filled and completely filled d-orbitals are more stable than partially filled d-orbitals. So Fe3+ is more stable than Fe2+.
Which one is more stable ferrous or ferric salts and why?
As half-filled 3d5 configuration is more stable, therefore, ferric salts are more stable then ferrous salts.
Why ferric ion is stable?
As iron only has twenty-six electrons the d orbital is not filled completely. So, we can say that a ferric d orbital is filled by 5 electrons, that is , half-filled and half-filled orbitals are stable. So, ferric is stable due to half-filled d orbital. The electronic configuration of iron is 1s22s22p63s23p64s23d6 .
Why is Fe3+ ion more stable than co3+ ion?
Fe3+ ion is more stable due to its half-filled 3d5 electron configuration. As half filled and completely filled shells are more stable Fe3+ ion is more stable.
Why Cu2+ is more stable than Cu+?
In an aqueous solution, a Cu2+ ion is more stable than a Cu+ ion due to the fact that the Cu2+ ion has a high negative value of hydration enthalpy. Means that more energy is released when Cu2+ is dissolved in water than in the case of Cu+. Hence it’s more stable.
Why is Fe2+ more easily oxidized to Fe3+?
Fe2+ is easily oxidized to Fe3+ . so Fe3+ should be more stable than Fe2+. This is because Fe3+has a half filled stable d5 configuration . so by oxidation Fe2+ converts its electron configuration from d6 to d5(more stable).
Which is more stable ferrous chloride or ferric chloride?
Explanation: The outermost electrons in 4s2 are readily given out to Chlorine. But it requires a further catalyst or oxidant like Oxygen or H2O2 etc, to give out an unpaired 3d^6 electron from d orbitals. In general , Ferric compounds are more stable as compared to Ferrous Fe compounds.
Why is ferric chloride more stable than ferrous chloride?
Which is the most stable complex?
[Fe(C2O4)3]3- is the most stable complex due to chelate formation as C2O42- is a bidentate chelating ligand.
Why CO3+ and ni3+ are unstable while Fe3+ is stable?
The Fe 3+ ion more stable than Fe 2+ ion because due to his electronic configuration i.e the electronic configuration of Fe 3+ has half filled last orbital and we know that half or fulled filled orbitals are most stable and here Fe 2+ has not half or full-filled orbital so Fe 3+ ion more stable than Fe 2+ ion.
Which is more stable Co2+ or CO3+?
This is because CO3+ has more tendency to form coordination complexes than Co2+. (c) The ions with d1 configuration can easily lose one more electron to acquire extra stability of d0 configuration.
