Hello guys
 

my question is following: what is the chemical formula for Cu-Cuprizone complex and how do I determine the solubility product?

I very rarely do this on this forum (some forums disallow it altogether,) but sometimes it is appropriate: you have a simple definition to determine, a quick Google search gives you the answer, why didn't you want to do that on your own?

I would like to know how to come to the formula.. Moreover, how do I know the soulubility product of it ? Google doe not know ith either

I would like to know how to come to the formula..

From its name.  Or by memorizing the reaction.  Or by looking it up.  Until we learn things like the periodic table, how does any student know anything?

Moreover, how do I know the soulubility product of it ?

You didn't ask for that at the beginning.  Google search leads to a number of PDF of research papers on this molecule.  That's not what you wanted?

Google doe not know ith either

Sure about that are we?

Hello guys,

I would like to know what the specific cirterias are in order to determine a chelate-complex from its formula.
One common thing is that they are large molecules with multiple C's involved (but why is it?; why do they have to be large?; why is Glycerin, for example, a chelate and [Al(OH)3(H2O)3] not, athough it got OH's involved as Glycerin?)
Furthermore: Can you determine the denticity of a chelate-complex by just looking at its formula? for example: C14H23N3O10 ...

Why is Al(OH)₃(H₂O)₃ not a chelate? What is the definition of a chelate?

[peterschmidt3943]

We have a chelate-complex, when a ligand with one or more free electrone pairs is availabe to bind with the central atom.

[mjc123]

No. A chelate is where a ligand binds to a metal atom at two or more sites (on the ligand). (That's why they are often relatively large, but don't have to be very large, e.g. oxalate C₂O₄^2- is a chelating ligand.)

A compound with multiple OH groups like glycerine can be a chelating ligand, but the individual OH^- or H₂O ligands in Al(OH)₃(H₂O)₃ are not.
