Selected Solubility Products and Formation Constants at 25^oC
Solubility Rules

Although all compounds have a characteristic solubility in water at a given temperature, some families of compounds are more soluble than others and it is useful to know certain general rules of solubility. We call any substance the solubility of which is less than 0.01 mol/L insoluble. If its solubility is greater than 0.1 mol/L, we call it soluble. If its solubility is between 0.01 and 0.1 mol/L, we say that it is slightly soluble. The following solubility rules can be used to determine solubilities in water, with the disclaimer that they don't always hold, nor do they include every ion which is in common use, but they are good to have nearby when needed:

1. All sodium, potassium, and ammonium salts are soluble.
2. All nitrates, acetates and perchlorates are soluble.
3. All silver, lead and mercury(I) salts are insoluble.
4. All chlorides, bromides and iodides are soluble.
5. All carbonates, sulfides, oxides and hydroxides are insoluble.
6. All sulfates are soluble except strontium sulfate and barium sulfate.

That having been said, here is a table of solubility product constants.

Why is NH3 not written as H3N?

In inorganic chemistry and especially in binary compounds they have the habit to use an order based on electronegativity: the least electronegative element being cited first.

• Sulfur hexafluoride: SF6
• Ammonia: NH3
• Calomel: Hg2Cl2
• Diborane: B2H6

As correctly commented by Eric Ressner Ammonia does not follow the simple electronegativity rule: electronegativity of nitrogen is 3.0 hydrogen is 2.2 (Linus Pauling scale).
So I double checked the guidance: the correct element sequence is ‘inspired by’ electronegativity, but with a few exceptions. This is detailed in Table VI (p 260 of the red book):

By convention, the later an element occurs when the table is traversed following the arrows, the more electropositive is the element.

Hydrogen is placed on top of Nitrogen. So NH3 is following the ‘rule’.
