In older homes (those constructed early in this century and before), not only were the walls, trim, and other wood components painted with lead-based paint, but almost all metals were primed with red lead or painted with lead-based paint. Lead may be present in milk-based (casein) and water-based paints (distemper and calcimines). It may also be contained in varnishes, which used lead acetate as a drying agent, as well as in window glazing putty.4... 

Lead antimonate [13510-89-9] (Naples yellow), Pb2(Sb0 2> mol wt 993.07, d = 6.58g/cm, is an orange-yeUow powder that is insoluble in water and dilute acids, but very slightly soluble in hydrochloric acid. Lead antimonates are modifiers for ferroelectric lead titanates, pigments in oil-base paints, and colorants for glasses and glazes (see Colorants for ceramics). They are made by the reaction of lead nitrate and potassium antimonate solutions, followed by concentration and crystallization. 

During the 1960s, Americans lived in a lead-drenched society. They fueled their cars with leaded, antiknock gasoline. They ate food and their babies drank milk from lead-soldered cans. They stored drinking water in lead-lined tanks and transported it through lead or lead-soldered pipes. They squeezed toothpaste from lead-lined tubes and poured wine from bottles sealed with lead-covered corks. They picked fruit sprayed with lead arsenate pesticide and served it on lead-glazed dishes in houses painted and puttied with lead-based compounds. 

Lead-based paint— Present on many surfaces in homes not recently rebuilt or remodeled Lead pipes— More common in older homes Lead solder— On pipes and water heaters Enameled or ceramic pots and dishware—Improper glazing can leach lead into foods Paper wrappings— Holiday paper and party decorations (10 g/kg)... 

Lead antimonate, Pb3(Sb04)2, is used as an orange pigment in oil-based paints and in glazes. Write a balanced chemical equation and a solubility product expression for its dissolution in water. 

Calculations were based on an average wind velocity of 6.4 miles per hour, which is typical for the San Diego area. The solution of the equation for four, five, and six layers of Tedlar glazing at three brine temperatures (100°, 125°, and 150°) and two ambient temperatures (55° and 70°) is presented in Table IV. Ground losses of 1 B.t.u./sq. ft. (day) (° F.) were based on the results obtained in the deep basin still (2) operated by the Battelle Memorial Institute for the Office of Salin, Water. in.El ori da..
