Why does increase in coordination number mean increase of solubility? Is it something to do with bonds releasing energy to form??- I don't get it-

thank you

Okay so I'm actually a GCSE student so I'm not up to explaining the detail (mainly because I have no idea whatsoever! xD) but:
Co-ordination number means the number of atoms bonded to an atom- so like in a covalent bond.
One of the factors of solubility is 'Common-Ion effect'- when one component in the solute (coordination number) is also in the solvent.
The more coordination number means more atoms --> more atoms added to the solution --> increase in solubility as there is more of the solute as they are in the solvent too, which makes the solution. (I think? Hope that helps )

For myself I explain it in that way: coordinations numbers show you, how many ligands (ions) are around the central ion as a bond. So the higher the coordination number, the more ligands are bonded to a central ion what means in turn the more of those ligands can be solved in solution until the satruation is done.
