Lead (II) - acetate ( Pb ( CH3COO ) 2), a colorless crystalline solid, the lead (II ) salt of acetic acid. In addition to the anhydrous substance also occurs trihydrate ( Pb ( CH3COO ) 2 · 3 H 2 O).

Representation

Lead (II ) acetate may be prepared by reaction of lead (II ) oxide produced with acetic acid

Use

Lead (II ) acetate is mainly used for production of other lead compounds, such as lead chromate ( chrome yellow ) and basic lead carbonate ( white lead ). Lead (II ) acetate is used as a detection reagent for sulfides.

Lead (II ) acetate is known as sugar of lead because it tastes sweet and is readily soluble in water. Despite its toxicity, lead sugar was until the 19th century as a sugar substitute ( defrutum ) used - in particular wine has been sweetened with it.

Ludwig van Beethoven's death by verpanschte wines has been controversial.

Lead paper, with a 1 % aqueous solution of lead acetate soaked and dried in hydrogen sulfide - free air filter paper is used for the qualitative detection of hydrogen sulfide (H2S), it develops brown gray, shiny metallic lead sulfide.
