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.

Predict the approximate wavelength and predominant color of light absorbed by the complex.arrow_forward
- Identify, based on the position in the periodic table, the actinide elements among those in the following list: Co, Cm, Cd, Ce, Cf.arrow_forwardThe transition metals form a class of compounds called metal carbonyls, an example of which is the tetrahedral complex Ni(CO)4. Given the following thermodynamic data (at 298 K): (a) Calculate the equilibrium constant for the formation of Ni(CO)4(g) from nickel metal and CO gas. (b) Is the reaction of Ni(s) and CO(g) product- or reactant-favored at equilibrium? (c) Is the reaction more or less product-favored at higher temperatures? How could this reaction be used in the purification of nickel metal?arrow_forward
