Lead chloride metasilicate

Small Quantities of Soluble Salts. Wear nitrile rubber gloves, laboratory coat, and eye protection. Dissolve the soluble lead salt (0.04 mol, e.g., 11 g of lead chloride) in water (200 mL) and add, while stirring, a solution of sodium metasilicate (Na2Si03-5H20, 25 g,... [Pg.323]

Lead and zinc sulfides have been produced by the standard technique in gels. The lead compounds are toxic and should be handled with care. For lead sulfide,25 26 the gel is prepared by mixing sodium metasilicate (sp gr 1.05) with 2.26 N HC1 to reach a pH of 6. A few drops of lead acetate or chloride solution are added to the gel before it is allowed to set. Setting requires about 1 week. The solution is then covered with a 1 M solution of thioacetamide. The thio-acetamide slowly releases hydrogen sulfide into the solution according to the... [Pg.5]
