WebThe elements of group 12 i.e., Zinc, Cadmium, and Mercury are generally not regarded as transition elements as their atoms and all ions formed have completely filled d-orbitals i.e., these do not have partially filled d-orbitals in atomic state or common oxidation state (Zn 2+, Cd 2+, Hg 2+). Zn (30) = [Ar] 4s 2 3d 10 Zn 2+ = [Ar] 3d 10 4s° WebDec 24, 2024 · In an aqueous medium, Cu2+ is more stable than Cu+. This is because although energy is required to remove one electron from Cu+ to Cu2+, high hydration …
WebCu ion is not stable in aqueous solution because large value of second ionisation enthalphy of copper is compenscited by much more negative hydration energy of C u … WebDec 17, 2012 · 1. Cu+ ion oxidizes and reduces simultaneously in aqueous solution to give Cu2+ and Cu ions. Therefore Cu+ ion is unstable in aqueous solution and it disproportionates readily to Cu2+ and Cu ions. 2. Ce belongs to the lanthanoid series. In lanthanoids +3 oxidation state is the most stable.
WebAug 15, 2024 · This test is very sensitive. The precipitate is soluble in aqueous ammonia. Note: Many metal ions form ferrocyanide precipitates, so potassium ferrocyanide is not … WebMar 12, 2024 · Answer: In an aqueous medium, Cu2+ is more stable than Cu+. This is because although energy is required to remove one electron from Cu+ to Cu2+, high …
WebNov 4, 2015 · However, this order does not hold for all solvents as the affinity of the solvating ion for Cu+ vs Cu 2+ will condition it (for example, Cu + will supersede Cu 2+ in acetonitrile).
WebCorrect option is A) Half filled and completely filled subshells are more stable. However Cu 2+ with 3d 9 electronic configuration is more stable than Cu + with 3d 10 electronic configuration. This is because electrode potential is more significant in determining stable oxidation state than electronic configuration.
