How do metal ions form salts and complexes?

Answer 1

By drafting in the appropriate ligands...........

Most transition metals' binary halides are somewhat soluble in aqueous solution, and the following reaction would be used to illustrate how they dissolve in water:

#MCl_2(s) + "excess water"rarrM^(2+)(aq) + 2Cl^(-)(aq)#

The cation in solution is a coordination complex of a metal ion, which we could represent as #[M(OH_2)_6]^(2+)#. Given the appropriate counterion, we could crystallize this species from solution, and, typically, we get an octahedral metal hydrate.

Due to its lability, different ligands could take the place of the water molecule.

Metal ions can form complexes by bonding with ligands through coordinate covalent bonds. The ligands donate electron pairs to the metal ion, forming a complex ion. Alternatively, metal ions can form salts by reacting with non-metal ions, usually anions, through ionic bonding. The metal ion donates electrons to the non-metal ion, forming an ionic compound.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
