WebIn 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 energy of Cu2+ compensates for it. ... Cu2+ ions has greater charge density than cu+ ions and hence forms much stronger bonds releasing more energy. 0 Thank You. Shruti Dadhwal 6 years, 2 … WebJul 14, 2024 · Comparing to Cu+, Cu2+ has a high density of positive charge .and the heat of hydration is increased as its charge density increases. So Cu2+ releases more heat …
NCERT Exemplar Class 12 Chemistry Solutions for Chapter 8
WebIt is due to high hydration energy of Cu2+. Stability of oxidation state depends upon 3 factors I.E ,ENTHAPY OF SUBLIMATION & HYDRATION ENTHALPY in case of Cu2+ hydration enthalpy is high & compensates for other factors. Cu2+ is stable in aqueous solution. in aqueous solution Cu+ disproportionates to Cu2+ and Cu. 2Cu+------>Cu2+ … WebCu2+ is more stable than Cu+.Stability depends on the hydration energy (enthalpy) of the ions when they bond to the water molecules. The Cu2+ ion has a greater charge density than Cu+ ion and thus forms much stronger bonds releasing more energy. The extra energy needed for the second ionization of the copper is more than compensated for by … get total number of rows pandas
Why is cu +2 is more stable than cu+ even after its d 9 orbital
WebIonic radius of I- = 216 pm is much bigger than size of copper cations (Do not have exact numbers). As we move from Cu+ to Cu2+ the size of cation decreases decreasing … WebFeb 7, 2024 · Assertion (A): Cu 2+ in water is more stable than Cu +. Reason (R): Enthalpy of hydration for Cu 2+ is much less than that of Cu +. In the light of the above … WebHalf 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 … get total seconds from datetime c#
