Solubility Rules for Inorganic Compounds

A set of vocabulary flashcards reviewing the solubility rules for inorganic compounds, including soluble and insoluble compound categories along with their specific exceptions.

Table I.1 Solubility Rules for Inorganic Compounds

A reference table summarizing the general solubility rules and exceptions for inorganic ionic compounds in aqueous solutions.

Solubility of Group 1 Elements and Ammonium Compounds

Soluble compounds containing Group 1 elements or ammonium ($\text{NH}_4^+$), which have no listed exceptions.

Solubility of Halides (Chlorides, Bromides, Iodides)

Soluble compounds containing chlorides ($\text{Cl}^-$), bromides ($\text{Br}^-$), or iodides ($\text{I}^-$), except those of $\text{Ag}^+$, $\text{Hg}_2^{2+}$, and $\text{Pb}^{2+}$.

Solubility of Nitrates, Acetates, Chlorates, and Perchlorates

Soluble compounds containing nitrates ($\text{NO}_3^-$), acetates ($\text{CH}_3\text{CO}_2^-$), chlorates ($\text{ClO}_3^-$), and perchlorates ($\text{ClO}_4^-$).

Solubility of Sulfates

Soluble compounds containing sulfates ($\text{SO}_4^{2-}$), except those of $\text{Ca}^{2+}$, $\text{Sr}^{2+}$, $\text{Ba}^{2+}$, $\text{Pb}^{2+}$, $\text{Hg}_2^{2+}$, and $\text{Ag}^+$.

Solubility of Carbonates, Chromates, Oxalates, and Phosphates

Insoluble compounds containing carbonates ($\text{CO}_3^{2-}$), chromates ($\text{CrO}_4^{2-}$), oxalates ($\text{C}_2\text{O}_4^{2-}$), and phosphates ($\text{PO}_4^{3-}$), except those of the Group 1 elements and $\text{NH}_4^+$.

Solubility of Sulfides

Insoluble compounds containing sulfides ($\text{S}^{2-}$), except those of the Group 1 and 2 elements and $\text{NH}_4^+$.

Solubility of Hydroxides and Oxides

Insoluble compounds containing hydroxides ($\text{OH}^-$) and oxides ($\text{O}^{2-}$), except those of the Group 1 elements and Group 2 elements later than Period 2.
