What is stepwise stability constant?
Each step is characterized by its individual equilibrium constant called stepwise formation constant or stepwise stability constant. For the formation of ML n complex from an aquated metal cation [M (H 2) n] +n and monodentate ligand L, there will be 'n' consecutive steps and 'n' stepwise formation constants.
How common is the decreasing trend in stepwise constants?
Copyright © Mandeep Dalal Now although the decreasing trend in stepwise constants is pretty much common in most of the complex formation processes, still some exceptions do exist in which it is found that Kn+1 > Kn.
What is the formation constant?
The formation constant or stability constant may be defined as the equilibrium constant for the formation of a complex in solution. The magnitude of ? n is actually a measure of the strength of the interaction between the ligands, which come
Why do stepwise formation constants decrease with entropy?
[Co(NH3)6]3 + > [Ni(CN)4]2 ? > [Cu(CN)4]3 ? > [Cr(OH)4] ?. You may notice that each stepwise formation constant is smaller than the one before it. This decreasing trend is due to the effects of entropy, causing each step to be progressively less likely to occur. You can think of this in the following way, continuing with the previous example:
