Lead(II) hydroxide (Pb(OH)₂, CAS 19783-14-3) is an inorganic compound that exists as a white amorphous or crystalline powder. It is sparingly soluble in water but soluble in acids and alkalis. It is typically prepared by the reaction of a soluble lead salt, such as lead nitrate or lead acetate, with an alkali hydroxide. The primary industrial application of lead(II) hydroxide is as a crucial precursor in the synthesis of various lead-based inorganic materials. It serves as a starting material for the production of lead oxides (e.g., PbO, Pb₃O₄), lead-based ceramics, and lead-containing glasses. It is also used in the formulation of certain pigments and as a component in some types of batteries. In laboratory settings, it finds use as a reagent for the precipitation and purification of other substances. Due to the toxicity of lead compounds, handling lead(II) hydroxide requires strict safety precautions, including the use of personal protective equipment and proper ventilation to prevent inhalation or ingestion. Its use is regulated in many applications due to environmental and health concerns associated with lead.
