How do solubility rules help us identify which product is the solid?

I am not quite sure what you are after......

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 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".............
