Concept introduction:
A complex ion is formed when a metal ion reacts with a Lewis base in solution. This reaction is defined in terms of
Metal ion which is positively charged functions as a Lewis acid. Lewis base or the ligandhas one or more lone pairs of electrons. For example, Cu2+,which is a highly charged and small metal ion having themajor tendency to function as Lewis acids, consequentlyexhibiting the greatest affinity to form complex ions.
(b)
Interpretation:
Equations which represent the given observation that when chromium metal is dissolved in HCl(aq), a blue solution is obtained which quickly turns into green color. After that, the green solution becomes blue-green and then violet should be determined.
Concept introduction:
A complex ion is formed when a metal ion reacts with a Lewis base in solution. This reaction is defined in terms of chemical equilibrium. A complexion comprises of a ligand and a metal ion as a result of an interaction of Lewis acid-base.
Metal ion which is positively charged functions as a Lewis acid. Lewis base or the ligand has one or more lone pairs of electrons. For example, Cu2+, which is a highly charged and small metal ion having the major tendency to function as Lewis acids, consequently exhibiting the greatest affinity to form complex ions.

- The standard reduction potential for the reaction [Co( H 2 O)6]3+(aq)+e[CO( H 2 O)6]2+(aq) is about 1.8 V. The reduction potential for the reaction [Co( NH 3 )6]3+(aq)+e[Co( NH 3 )6]2+(aq) is +0.1 V. Calculate the cell potentials to show whether the complex ions,. [Co( H 2 O)6]2+ and or [Co( NH 3 )6]2+, can be oxidized to the corresponding Cobalt (III) complex by oxygen.arrow_forwardWould you expect salts of the gold(I) ion, Au+, to be colored?
