PbCl4

Lead tetrachloride, also known as lead(IV) chloride, is an inorganic compound with the chemical formula PbCl4. It is a yellow crystalline solid that is highly reactive and sensitive to light and moisture. Lead tetrachloride is formed when lead is exposed to chlorine gas or when lead chloride is treated with chlorine. It is a strong oxidizing agent and can react with various organic and inorganic substances.

The compound is primarily used in the production of lead dioxide, which is a component in the positive plates of lead-acid batteries. It is also used in the synthesis of other lead compounds and as a catalyst in certain chemical reactions. Lead tetrachloride is toxic and can cause severe health issues if ingested or inhaled. It is important to handle this compound with care and follow appropriate safety protocols.

Lead tetrachloride is not stable at room temperature and tends to decompose into lead chloride and chlorine gas. It is also highly soluble in water, forming a yellow solution. The compound has a molar mass of 323.1 g/mol and a density of approximately 3.6 g/cm³. Its melting point is around 300°C, and it sublimes at higher temperatures.
