Lead Acetate Subacetate Solution

Copper and Iron, — On acidifying 10 cc. of lead subacetate solution with 2 cc. of dilute acetic acid, and adding potassium ferrocyanide solution, a precipitate forms which should have a pure white color. 

Lead Glycocholate, (CieHnNOg) Pb( ), is formed as a white, flocculent precipitate, when solution of lead subacetate is added to a solution of a glycocholate or of glycocholic acid with the-neutral acetate the precipitation does not occur in the presence of an excess of acetic acid. It is soluble in alcohol, and in an excess of lead acetate solution. 

The plumbi carboma (U. S, Br.), or white lead or ccrusc, is a basic carbonate, (PbCO,) PbH,0,—774.7—mixed with varjing proportions of other basic carl nates. It is usually prepared by the action of CO. on a solution of the subacetate, prepared by the action of acetic acid on Po and PbO. It is a heavy, white powder insoluble in H,0, except in the presence of CO, soluble in a< a with efiervescenoe and decomposed by heat into CO, and PbO.
