Is Cu+ stable in water?
Cu+ is not stable in aqueous solution because it disproportionates in water to form Cu2+ and Cu. One of the possible driving forces for this disproportion reaction is the formation of metal Cu which has extra stability in water.
Why does Cu+ ion undergoes disproportionation in water?
Cu+ ion is unstable in aqueous solution because the hydration energy of Cu+2 is greater than Cu+ ion which compensates for the energy required for the loss of electron. Hence Cu+ ion undergoes disproportion reaction in water to form Cu+2 ion and Cu .
Why does Cu+ undergo disproportionation?
Aqurated copper (I) catin undergoes disproportionation as 2Cu^(+)(aq) rarr Cu^(2+) (aq) + Cu, because. hydration energy of Cu2+ is higher than that of Cu+ which compensates second ionisation energy of Cu.
Why is Ag+ more stable than Ag2+?
Explanation: Ag+ is more stable than Ag2+ Cation due to the complete Ag+ configuration. An oxidizing agent always tends to accept the electrons. It is extremely volatile and therefore easily accepts electrons to achieve a more stable + 1 oxidation state.
Will Cu+ undergo disproportionation in aqueous medium?
Although Cu+ disproportionates in aqueous solution as 2Cu+(aq)→Cu(s)+Cu2+(aq).
Why d1 configuration is very unstable in ions?
The ions in d1 configuration tend to lose one more electron to get into stable d0 configuration. Also, the hydration or lattice energy is more than sufficient to remove the only electron present in the d-orbital of these ions. Therefore, they act as reducing agents.
Why Ag+ is more stable?
Is Ag+ stable?
Re: Electron configuration fo Ag+ The element is much more stable and has a lower energy when the 4d orbital is filled, so one electron is placed there, rather than in the 5s orbital. When it is ionized, the electron is removed from the outermost shell, which is the 5s orbital.
Can Cu+ show disproportionation?
Cu^+ is not stable and undergoes disproportionation. E^o for Cu^+ disproportionation is : (E^oCu^2 + /Cu^+ = + 0.153V, E^oCu^+/Cu = 0.53V)
Why is Cu2+ more stable than cu+ in aqueous solution?
In an aqueous medium, Cu 2+ is more stable than Cu +. This is because although energy is required to remove one electron from Cu + to Cu 2+, high hydration energy of Cu 2+ compensates for it. Therefore, Cu + ion in an aqueous solution is unstable. It disproportionates to give Cu 2+ and Cu.
Why is the hydration enthalpy of Cu(2+) greater than Cu(1+)?
A Cu (2+) ion is smaller in size compared to Cu (1+) or elemental Cu.So the hydration enthalpy of the former is always greater than the others.This means the driving force of the disproportionation of Cu (1+) to Cu and Cu (2+) is the greater amount of energy released in the product formation.
What is the stability of ionic compounds in aqueous conditions?
Stability in aqueous conditions depends on the hydration energy of the ions when they bond to the water molecules (an exothermic process). The C u X 2 + ion has a greater charge density than the C u X + ion and so forms much stronger bonds releasing more energy.
Why is C u x 2 + more stable than C U(S)2+?
A nearby C u X + ion is the most facile reduction target for the removed electron, which is why C u ( s) is also formed. Hence, C u X 2 + is more stable than C u X + in aqueous medium.
