Ólomdioxid

Ólomdioxid, also known as lead dioxide, has the chemical formula PbO2. It is an inorganic compound that exists as a brown or black solid. Ólomdioxid is a strong oxidizing agent and plays a role in various chemical reactions. It is insoluble in water but dissolves in concentrated acids and bases.

Historically, ólomdioxid has been used in the manufacture of matches and fireworks due to its oxidizing properties. It also finds application as a component in lead-acid batteries, where it acts as the positive electrode material. The chemical reactions within these batteries involve the reversible conversion of ólomdioxid. Another notable use is in the production of certain pigments and in some types of chemical analysis.

Exposure to ólomdioxid, like other lead compounds, can be harmful. Lead is a toxic heavy metal, and precautions should be taken to avoid inhalation or ingestion. Industrial handling of ólomdioxid requires appropriate safety measures. The environmental impact of lead compounds is also a concern, and efforts are made to minimize lead pollution.
