How do you differentiate inorganic salts by precipitation with different anions?
Unfortunately, solubility is pretty random, and it's hard to give you a pattern on the periodic table for everything. You may have to memorize most, but there are some helpful exceptions!
In group 2A, Ca, Sr, and Ba (all right next to each other) cations coupled with
Honestly, rather than throw so much information that I memorized at you, you should search "Solubility Guidelines for Common Ionic Compounds in Water" and stare at and practice with that table for a few days to totally understand this. It's a lot!
For general rules of solubility we can advance the following generalities......mostly it is based on the solubilities where the COUNTERION,
All the salts of the alkali metals and ammonium are soluble.
All nitrates, and perchlorates are soluble.
All halides are soluble EXCEPT for
All sulfates are soluble EXCEPT for
All carbonates and hydroxides are insoluble. All sulfides and oxides are insoluble; transition metal oxides, and main group metal oxides routinely tend to be as soluble as bricks.
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
