Solutions need to be fully soluble and should be relatively dilute, typically ~0.1 M. Reagents should be slowly added drop-wise and observed carefully. The term is used both in inorganic chemistry and organic chemistry. However, all that information can be placed in a table as shown below, which makes it easier to locate solubility information for a particular ionic compound made up of a particular cation and a particular anion.

In inorganic chemistry, the phosphate ion combines one phosphorus atom with three or four oxygen atoms, forming the base for many different salts. 3. Because it is insoluble in water we know that it is the precipitate. It reacts slowly with gastric acid to form soluble aluminium salts and phosphoric acid. Here is the solubility product expression for calcium phosphate again: The units this time will be: (mol dm-3) 3 x (mol dm-3) 2 = (mol dm-3) 5 = mol 5 dm-15. 293.15 K).
