ólomszulfáttá

ólomszulfáttá is the Hungarian name for lead(II) sulfate. It is an inorganic compound with the chemical formula PbSO4. Lead(II) sulfate is a white crystalline solid that is practically insoluble in water and ethanol. It is soluble in concentrated acids, such as hydrochloric acid, and in solutions of ammonium acetate.

Historically, lead(II) sulfate was used as a white pigment in paints, known as "white lead," although its toxicity has led to its replacement by other pigments. It is a key component in lead-acid batteries, where it forms on the electrodes during discharge. This reversible reaction is fundamental to the battery's operation.

Lead(II) sulfate can be found naturally as the mineral anglesite. It is formed through the oxidation of lead sulfide minerals, such as galena, in the presence of sulfate ions. Due to the toxicity of lead compounds, proper handling and disposal procedures are essential when working with lead(II) sulfate. Environmental regulations often limit its use and emission. Its presence in the environment can be an indicator of lead pollution.
