    Iron (II) compounds tend to be oxidized to iron (III) compounds in the air. Iron reacts with oxygen in the air to form various oxide and hydroxide compounds; the most common are iron (II,III) oxide (Fe 3 O 4) and iron (III) oxide (Fe 2 O 3). Iron (II) oxide also exists, although it is unstable at room temperature.
