Discuss each of the following observations: (a) Although Co 2+ (aq) forms the tetrahedral complex [CoCl 4
Question:
Discuss each of the following observations:
(a) Although Co2+ (aq) forms the tetrahedral complex [CoCl4]2− on treatment with concentrated HCl, Ni2+ (aq) does not form a similar complex.
(b) E° for the half-reaction:
depends on the pH of the solution, being most positive in strongly acidic medium.
(c) E° for the Mn3+/Mn2+ couple is much more positive than that for Cr3+/Cr2+ or Fe3+/Fe2+.
