WebThe one most commonly formed when it reacts with oxygen is lead (II) oxide, also known as lead monoxide. However, it may also form tri-lead tetroxide, sometimes called red lead, or lead (IV) oxide, also known as lead dioxide. The lead oxides produced in this reaction appear as a red, yellow or dark brown powder, and are insoluble in water.
