Lead Nitrate

Whatsapp Order

 Lead Nitrate is a white crystalline inorganic compound composed of lead and nitrate ions. It is highly soluble in water and commonly used in laboratories and industrial applications as an oxidizing agent, in the preparation of other lead compounds, and as a reagent in chemical synthesis. Lead Nitrate is known for its strong oxidizing properties and must be handled with care due to its toxicity and environmental hazards.
