CAS 1309-60-0

Dióxido de plomo

Descripción:

Dióxido de plomo, con el número CAS 1309-60-0, es un compuesto inorgánico caracterizado por su apariencia de marrón oscuro a negro y su fórmula química PbO2. Es un agente oxidante fuerte y se utiliza principalmente en baterías de plomo-ácido, donde sirve como material de la placa positiva. Dióxido de plomo es insoluble en agua pero puede disolverse en ácidos fuertes, formando iones de plomo(II) y otros compuestos de plomo. El compuesto exhibe una estructura cristalina tetragonal y tiene un alto punto de fusión, lo que lo hace estable en diversas condiciones. Su estado de oxidación de +4 en Dióxido de plomo contribuye a su reactividad, particularmente en reacciones redox. Debido a su naturaleza tóxica, Dióxido de plomo plantea riesgos para la salud y el medio ambiente, lo que requiere un manejo y disposición cuidadosos. Además, puede participar en varias reacciones químicas, incluida la oxidación de compuestos orgánicos y la síntesis de otros materiales a base de plomo. En general, Dióxido de plomo es significativo en aplicaciones industriales, particularmente en almacenamiento de energía y electroquímica.

Lead Dioxide

CAS: 1309-60-0

Lead dioxide is a compound with the chemical formula PbO. It is used in wastewater treatment and as a pigment in paints and enamels. Lead dioxide is insoluble in water and has a high surface tension, which allows it to be used as an anti-fouling agent by coating the inside of sewage pipes. The solubility of lead dioxide decreases with an increase in temperature, so it precipitates at higher temperatures due to its low solubility. Lead dioxide is thermodynamically stable up to about 400 degrees Celsius. It reacts with water through transfer reactions, where the lead is oxidized to PbO2+ ions. Lead dioxide has a hydrophobic effect, which may be due to its ability to form clathrates with organic molecules. It can also react with other substances such as CO2, HCl and NH3 to form lead salts. Lead dioxide can also be used as an optical sensor or thermometer because of its dependence on temperature for phase transition
