grade,is a crystalline product ofhigh assay and high purity,containingover 40%available sulfide.It is verysoluble in water,alcohol and benzene,hydrolyzing smoothly in either acidic oralkaline solution to provide a convenientsource of sulfide ion for both the quanti-tative and qualitative separation of theions of heavy metals.  \ndense,easily filterable,and the rate ofprecipitation can be more easily controlled.Baker Thioacetamide is ideal for class-room use,particularly when a hood is notemployed.%4 pound may suffice for 50students for the usual semester qualita-tive course.  \nBaker Thioacetamide Reagent,Crystal,is packaged in 1 ounce,  pound,and 1pound amber glass bottles.Like all 'BakerAnalyzed'Reagents,each label bears theactual lot analysis of the contents.  \nThioacetamide is rapidly supplanting gas-eous hydrogen sulfide as a precipitant be-cause of its ease-of-use and freedom fromnoxious and corrosive properties.Sulfidesprecipitated by Thioacetamide-unlikethose with H₂S-are coarsely crystalline,  \nFREEFor reprints of the Thioacetamide reviewand articles from CHEMIST-ANALYST,write J.T.Baker Chemical Company,Dept.R-V,Phiillipsburg,New Jersey.  \nBaker
