Why is Cu+ not in aqueous solution?
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 . Hope it helps you!!
Why are Zn 2 salts white?
Zn2+(3d10) salts have no impaired electrons but Cu2-(3d9) salts have one unpaired electrons. Hence Zn2+ salts are white while Cu2- salts are coloured.
Which ion is more stable in aqueous solution and why?
In aqueous, transition metal ions exist as complex ions: [M(H2O)6]n+ . Since H2O is a weak field ligand, electrons keep them unpaired as far as possible. Cr3+ ion is the most stable in aqueous solution on account of maximum crystal field stabilization energy.
Why is Mn 2 stable?
Complete answer: As we can see that on removal of two electrons, manganese have a configuration where d-block is half filled. We know that half filled and fully filled orbitals are more stable than any other configuration. Therefore, Mn+2 is stable at this oxidation state.
What MnO4 called?
Permanganate | MnO4- – PubChem.
What is oxidation number of MnO4?
+7
What is the chemical formula of permanganate?
KMnO₄
Why is MnO4 ion Coloured?
Due to the charge transfer in the molecule, an electron absorbs photons from the surroundings and gets promoted to the empty d orbital of manganese ion from the highest energy molecular orbital of the bond and is responsible for the colour.
