Could someone give me a list of precipitates for the following ions : $Hg^+,Hg_2^{2+},Cr^{2+},Cr^{3+},Mn^{2+,3+,4+,5+,6+,7+},Co^{2+,3+},Ni^{2+,3+}$ (the list must include the precipitate's colour too) ?

Are you joking? Have you not got an inorganic text?

Explanation:

There are general rules for assessing solubilities in aqueous solution:

All the salts of the $"alkali metals"$ and $"ammonium"$ are soluble;

All $"nitrates"$ , and $"perchlorates"$ are soluble.

All $"halides"$ are soluble EXCEPT for $AgX, Hg_2X_2, PbX_2"$ .

All $"sulfates"$ are soluble EXCEPT for $PbSO_4, BaSO_4, HgSO_4$ .

All $"oxides, carbonates, and hydroxides are insoluble"$ . All $"sulfides"$ are insoluble.

The given rules follow a hierarchy. Alkali metal and ammonium salts tend to be soluble in all circumstances. The one exception to this rule is $K^(+)""^(-)BPh_4$ and $NH_4^(+)""^(-)BPh_4$ , both of which are as soluble as bricks. $Na^+""^(-)BPh_4$ , the which has some aqueous solubility, is sold as $"kalignost"$ , i.e. $"potassium recognizer"$ .............

Your question is far too open-ended.....
