pliiumdioksüüd

Pliiumdioksüüd is the Estonian name for lead dioxide. It is a chemical compound with the formula PbO₂. It appears as a brown or reddish-brown solid. Lead dioxide is an amphoteric oxide, meaning it can react with both acids and bases. It is a strong oxidizing agent and is relatively insoluble in water. It can be produced through various chemical processes, often involving the oxidation of lead compounds. Historically, it has found applications in batteries, particularly in lead-acid batteries where it acts as the positive electrode material. It has also been used in matches and fireworks as an oxidizer. Due to the toxicity of lead, the use of lead dioxide has declined in many applications and is subject to strict regulations. Exposure to lead compounds can pose significant health risks.
