Name the following substances.

a) [Cu(Cl4]2- - tetrachloridecopper(II) ion

b) Ag(NH3)2+ - diamminesilver ion

c) Cu(NH3)4SO4 - tetraamminecoppersulfate (or tetraamminecopper(II) sulfate)

d) Al(H2O)6Cl3 - hexaaquoaluminum(III) trichloride

I have no idea if any of these are right, but someone please help me out if there not.
Thanks.

'chloro', not 'chloride'. Also, since this is an anionic complex, it should be 'cuprate'.

Missing oxidation number for silver.

Second try is better.

There should be no "tri" (in trichloride) - just "chloride" is sufficient. The number of chloride ions (ie.: 3) is determined by the oxidation number of the cation and the number of other ligands, if they are charged.
