CAS 1309-60-0

Diossido di piombo

Descrizione:

Diossido di piombo, con il numero CAS 1309-60-0, è un composto inorganico caratterizzato dal suo aspetto marrone scuro a nero e dalla sua formula chimica PbO2. È un forte agente ossidante ed è utilizzato principalmente nelle batterie al piombo-acido, dove funge da materiale per la piastra positiva. Diossido di piombo è insolubile in acqua ma può dissolversi in acidi forti, formando ioni di piombo(II) e altri composti di piombo. Il composto presenta una struttura cristallina tetragonale e ha un alto punto di fusione, rendendolo stabile in varie condizioni. Il suo stato di ossidazione di +4 in Diossido di piombo contribuisce alla sua reattività, in particolare nelle reazioni redox. A causa della sua natura tossica, Diossido di piombo presenta rischi per la salute e per l'ambiente, richiedendo un'attenta manipolazione e smaltimento. Inoltre, può partecipare a varie reazioni chimiche, inclusa l'ossidazione di composti organici e la sintesi di altri materiali a base di piombo. In generale, Diossido di piombo è significativo nelle applicazioni industriali, in particolare nello stoccaggio di energia e nell'elettrochimica.

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
