It also is readily prepared by adding a soluble chromate such as sodium or potassium chromate to a solution of lead nitrate, lead acetate or other soluble lead(II) salt in neutral or slightly acidic solution: Pb2+ + CrO42¯→ PbCrO4 The yellow precipitate is filtered, washed and dried....
Two water-soluble lead salts (lead acetate and lead nitrate) are usually used to react with CO32− in the solution for precipitation (equations 5–7 in the Supplementary Material). Lead acetate can be easily produced through the reaction of PbO and acetic acid (vinegar), of which the ...
consisting of a polybasic lead salt of a di- or a tri-nitro- substituted resorcinol containing 3, 4, 5 or 6 atoms of lead per aromatic nucleus in which a minor proportion of finely- divided boron is entrained within, and dispensed throughout, individual crystals of the polybasic lead salt...

(When checking some eggs with large specific gravity, such as porcine pulmonary filariasis eggs, saturated solutions such as magnesium sulfate, sodium thiosulfate and lead nitrate with large specific gravity can be used as floating solution instead of saturated salt water.) ...
While not wishing to be bound by theory, a carbon particle comprising small pore sizes (i.e., pore lengths) may have the advantage of decreased diffusion distances to facilitate impregnation of lead or a lead salt. For example, it is believed that the employment of carbon particles with a ...
For example in U.S. Pat. No. 3,119,880, patentee describes the Guerbet reaction in the presence of an alkali, a lead salt at least partially soluble in the reactant alcohol and, optionally a nickel dehydrogenation catalyst. Patentee employes various lead salts such as the nitrate, acetate...
Graphite oxide was prepared by oxidation of graphite flakes with sulfuric acid, sodium nitrate, and potassium permanganate at a ratio of 4:1:0.05 at 30° C. for 48 hours, according to the method of Hummers [U.S. Pat. No. 2,798,878, Jul. 9, 1957]. Upon completion of the reaction,...
