Description

General description

Lead (II) oxide is an oxide of lead with lead in +2 oxidation state. It is amphoteric in nature, capable of reacting with both acid and base.[1] It exists in two forms, litharge and massicot.[2] Lead (II) oxide is commonly used in making lead glass, lead white and red lead.[3]
