Oxides and Their Reactions

Study Notes

Oxides

Non-metal oxides do not contain any metal. They are acidic. Examples include $CO_2$, $SO_2$, $N_2O_3$ and $SO_3$.
Acidic oxides react with water to produce acids. For example, $CO_2$ reacts with water to form carbonic acid ($H_2CO_3$).
Acidic oxides react with a base to produce salt and water. For example, $CO_2$ reacts with $NaOH$ to form $Na_2CO_3$ and water.
Acidic oxides react with metal oxides to form salts. For example, $CO_2$ reacts with $CaO$ to form $CaCO_3$.
Basic oxides react with water to produce bases. For example, $Li_2O$ reacts with water to produce $2LiOH$.
Basic oxides react with acids to form salts and water. For example, $BaO$ reacts with $H_2SO_4$ to form $BaSO_4$ and water.
Basic oxides react with non-metal oxides to form salts. For example, $CaO$ reacts with $CO_2$ to form $CaCO_3$.
Amphoteric oxides behave as both acidic and basic. These oxides will react with both acids and bases and form salts and water. An example of this oxide is $Al_2O_3$.

Properties of Different Compounds

Neutral oxides do not show acidic or basic properties. Examples include $Al(OH)_3$, $H_2O$, $CO$, $H_2O$ and $NO$.
Peroxides are oxides where oxygen has an oxidation number of -1. Examples include $H_2O_2$, $Na_2O_2$, $CaO_2$ and $BaO_2$.
Peroxides are powerful oxidizing agents. They lose oxygen to form other compounds.
Lead sulfide ($PbS$) reacts with sulfuric acid ($H_2SO_4$) to produce lead sulfate ($PbSO_4$) and water ($H_2O$).
Hydrogen peroxide ($H_2O_2$) is a strong oxidizing agent and can be used as an antiseptic, bleaching agent for dyes, and oxidizes $PbS$ (lead sulfide) to form a white compound. The reaction is $PbS + 4H_2O_2 \rightarrow PbSO_4 + 4H_2O$.

Acids

Acetic acid is commonly found in vinegar.
Phosphoric acid is used for flavoring carbonated beverages.
Diprotic acids can release two $H^+$ ions per molecule.
Triprotic acids can release three $H^+$ ions per molecule.
Monoprotic acids contain only one hydrogen atom per molecule.
Polyprotic acids contain two or more hydrogen atoms per molecule.
