Explain why cu+ ion is not stable in aqueous

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° WebIn an aqueous medium, Cu2+ is more stable than Cu+. This is because energy is required to remove one electron from Cu+ to Cu2+, high hydration energy of Cu2+ compensates for it. Therefore, Cu+ ion in an aqueous solution is unstable. It disproportionates to give Cu2+ and Cu. Suggest Corrections.

WebFeb 26, 2024 · The stability gained by energy loss in hydration is more stabilising than the destabilising effect of the removal of 2 electrons. Also, as mentioned earlier, the greater the charge on the ion greater is its tendency to attract and keep the water molecules solvated to it. Cu2+ having a greater charge has a greater tendency of hydration than Cu+. WebApr 21, 2024 · Solution 1. You are quite correct in that it appears at first sight that $\ce {Cu+}$ should be more stable than $\ce {Cu^2+}$, but in aqueous media it isn’t. Stability in aqueous conditions depends on the hydration energy of the ions when they bond to the water molecules (an exothermic process). The $\ce {Cu^2+}$ ion has a greater charge ...
