    I am completely baffled by how we are meant to work out observations of ligand substitutions , if anyone has any tips/rules or even use this question to aid your explanation;e.g. [Cu(H2O)6]^2+(aq) + 4Cl^-(aq) --> [CuCl4]^2-(aq) +6H2O(l) (i)describe the observations that would be made during the addition of the concentrated HCl.

    You cannot "work them out", you have to learn them.

    In your example the pale blue hexaaqua copper(II) ion accepts chloride ligands and becomes the bright green tetrachlorocuprate(II) complex ion.

    That would depend on your spec. Which is also where you'll find the ones you'll be expected to know listed.
