If you make a cathodic electrodeposition of a transition metal (any) ion dissolved in an aqueous solution, what would be an example of an effective anode and why?
Anode should be the solid transition metal which is present as cation in the solution. For example if the solution in the electro deposition process is copper sulphate then solid copper should be selected as anode . This is because concentration of copper ions in the solution remain same throughout the process .As a result of this deposition is perfectly done.

When the transition metal materials are dissolved in the aqueous solution (e.g. Cu(NO3)2, Fe(NO3)3, K2CrO4, NiSO4), the solutions have color(such as blue, green and yellow color). Why do transition metal complexes make colored compounds in solution? Describe the relevant theory and reasons.
Unknown E is a transition metal halide of the metal in A. The metal ion has the electron configuration [Ar]3d6. What is the identity of E?
aqueous solution of transition metal aqua ions are often acidic. what factors must be taken into account in rationalizing the acidity of these ions?
The aqueous solutions of the transition metal salts are acidic as a result of hydrolysis of their hydrated cations. The H2O in these hydrated cations can form different colors in the solution of colmplex ions by entering ligand exchange reaction with different ligands like CI, NH3 SO Cu2+ Fe2+ Cr3+ Ni2+ Co2+ Mn2+ Al3+ V3+ Sc3+ salts are separately a)Write down water-solubility / hydration reactions. b)Write down the hydrolysis reactions and explain the reason for the acidity according to the...
