Lead(II) Oxide, with the chemical formula PbO, is a yellow or red solid that occurs naturally as the mineral massicot. It is commonly used in the production of glass, ceramics, and as a pigment in paints due to its ability to enhance color and durability. In addition to its industrial applications, Lead(II) Oxide plays a role in the manufacturing of lead-acid batteries, where it serves as a key component in the positive electrode. However, due to the toxicity of lead, safety precautions are essential when handling this compound to prevent health risks.
