Acetic acid and lead (II) nitrate react in solution to form a solution of lead (II) acetate. 2CH3CO2H + Pb(NO3)2 ---> Pb(CH3CO2)2 + 2HNO3 Lead acetate is soluble in water, through the formation of its trihydrate, Pb(CH3CO2)2•3H2O, a colorless or white substance. This solution is also known as sugar of lead, thanks to its sweet taste, though it is extremely poisonous. Crystals of lead (II) acetate may, however, be precipitated by concentrating this solution followed by slow cooling. Lead acetate solution is used to prepare other lead compounds like lead chromate or lead iodide and also in analytical chemistry.
