Chemical compound

Lead(II) bromide is the stable salt of lead and hydrobromic acid. It is typically formed by precipitation from lead(II) nitrate by the addition of a water-soluble bromide. As a chemical compound containing lead, it is categorized as probably carcinogenic to humans (Category 2A), by the International Agency for Research on Cancer (IARC). At room temperature it is a white powder. On strong heating, it melts at 367°C to form a colourless liquid that is a weak electrical conductor. The powder is weakly soluble in water (0.455g dissolves in 100g of water at 0°C). However, its solubility rises at higher temperatures and it is about ten times more soluble in boiling water.
