What is the process involving white lead used in lead-based paint production?

The process involving white lead in lead-based paint production is oxidation. White lead is primarily composed of basic lead carbonate or lead (II) carbonate, which is produced by oxidizing lead oxide. During the manufacturing process, lead oxide (a solid) reacts with carbon dioxide and moisture in the air to form the white lead pigment. This oxidation process is vital because it transforms lead oxide into a stable, non-toxic chemical form that is safe for paint applications, which is essential in ensuring the integrity and performance of the paint.

Fermentation, distillation, and sublimation do not pertain to the production of lead-based paint. Fermentation refers to the biochemical conversion of sugars into acids, gases, or alcohol by microorganisms, typically used in food and beverage production. Distillation is the process of separating components in mixtures based on their boiling points, often used in the purification of liquids. Sublimation is the transition of a substance from solid to gas without passing through a liquid state, which is not relevant to the chemical reactions involved in paint production with lead.
