lyijysulfaatti

Lyijysulfaatti, also known by its chemical formula PbSO4, is an inorganic compound. It appears as a white crystalline solid and is generally insoluble in water. Lyijysulfaatti occurs naturally as the mineral anglesite. It is a common component in lead-acid batteries, where it forms on the electrodes during discharge.

The compound can be produced through various chemical reactions, such as the precipitation of lead ions from a solution with sulfate ions. For instance, mixing a soluble lead salt like lead(II) nitrate with a soluble sulfate salt like sodium sulfate will result in the formation of lyijysulfaatti precipitate.

Historically, lyijysulfaatti has had various applications. Due to its white color and opacity, it was once used as a pigment, particularly in paints, under the name "white lead." However, its use has significantly declined due to its toxicity. Lyijysulfaatti is a toxic substance, and exposure can lead to lead poisoning. Therefore, its handling and disposal require strict safety measures. Its primary modern use remains within the battery industry.
