How do you dissolve lead acetate in water?
Wash once with water and vacuum dry, then wash twice with alcohol, and finally with ether. Let the solid dry in air. A number of reagent solutions are required for this procedure. A Lead Acetate Solution is prepared by dissolving 40 g Pb(CH3COO)2ยท3H2O in water, adding 0.5 mL CH3COOH, and diluting to 100 mL.

Does lead react with vinegar?
Lead does not react with most acids very quickly (save for nitric acid), due to low solubility of the lead salts and the low position of lead in the reactivity series of metals. But it will, slowly, react with acetic acid (vinegar) producing a solution of Pb+2 ions.
Is lead acetate reducing agent?
