The solubility of ionic compounds in water at 25☌, in general:

Use the solubility rules (list, table or chart) to decide if either of the ionic compounds are insoluble and will therefore form a precipitate.

List the possible ionic compounds that could be produced.

List the anions and cations in the solution.

Solubility Rules can be used to decide if a precipitate (an insoluble substance) will form from an aqueous solution at 25☌:.

Solubility Rules can be given as a list, a table, or a chart.

Precipitate of a salt is indicated by placing the letter s in round brackets, (s), to the right of the formula for the ionic compound. 3 The result is a precipitate, an insoluble solid. An ionic substance that does not dissolve in water is said to be insoluble.2 The result is an aqueous solution.Īqueous solution of a salt is indicated by placing the letters aq in round brackets, (aq), to the right of the formula for the ionic compound. An ionic compound that does dissolve in water is said to be soluble.Solubility rules are qualitative rules to determine whether an ionic compound will, or will not, dissolve in water at 25☌.
