Borek said:You have a huge excess of cyanide - so you can safely assume its concentration doesn't change (after dilution).
For the same reason - and taking into account quite large formation constant - you can safely assume all copper is complexed.
That gives you approximate, but quite reasonable values for two concentrations. There is only one unknown now.
After you are done, you should check if the assumptions hold.
Hemolymph said:Ok, so I did that
I got the Concentration of of copper cyanide to be 1.28E7
A formation constant, also known as stability constant, is a measure of the strength of the interaction between two chemical species. It quantifies the stability of a complex formed between a metal ion and a ligand.
Formation constant is useful in calculating end concentration because it allows us to determine the equilibrium concentrations of a complex formed between a metal ion and a ligand. By using the formation constant and the initial concentrations of the reactants, we can calculate the concentration of the complex at equilibrium.
The formula for calculating end concentration using formation constant is C = K * A * B, where C is the concentration of the complex, K is the formation constant, and A and B are the initial concentrations of the metal ion and ligand, respectively.
No, formation constant is specifically used for reactions involving the formation of a complex between a metal ion and a ligand. It cannot be applied to other types of chemical reactions.
Temperature can affect the formation constant by changing the energy of the reaction. Generally, an increase in temperature leads to an increase in the formation constant, indicating a stronger interaction between the metal ion and ligand. However, this is not always the case and the effect of temperature on formation constant can vary depending on the specific reaction and conditions.
