The solubility and activity coefficients of lead chloride in aqueous potassium nitrate solutions, at 25 °C and at boiling, are reported. The activity product constant of lead chloride at boiling has been determined. The Pitzer equations have been applied to the system and have allowed us to ...
14–16 The raw materials used were lead nitrate, zirconyl chloride octahydrate, titanium dioxide and potassium hydroxide; the amounts for a 500 ml autoclave are listed in Table 4.2. Like the TiCl4 solution process, this process also has two steps. The material in the autoclave is also the...
after adding potassium sulfate solution, can generate PbSO4 precipitation. After the separation of precipitate, the mother liquor is subject to treatment to remove Zn2 +, Fe3 +, Cu2 + and other impurities and can yield potassium nitrate after concentration. Lead sulfate, under the action of th...
According to Vauquelin (1809), it was prepared by adding lead acetate or lead nitrate to potassium chromate, and the shade of the precipitate could be varied (from yellow to orange or red) by adjusting the acidity/alkalinity of the products. Lead chromate( VI), which occurs naturally as ...
Lead does not evolve hydrogen readily with acids. Nitric acid attacks the metal readily, forming lead nitrate and oxides of nitrogen: 3Pb + 8HNO3 → 3Pb(NO3)2 + 2NO + 4H2O This reaction is faster in dilute nitric acid than strong acid. Hydrochloric acid has little effect on the metal...

The thermal decomposition of lead(II) nitrite is the key reaction; this compound apparently being formed from lead(II) nitrate and chloride by anion exchange and from red lead on removal of lead(II) cations. Lead(IV), as oxide or oxyanion, oxidises nitrite to nitrate, while lead(II) ...
ProductionLead chromate is found naturally in minerals crocoite and phoenicochroite. 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: ...
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 ...
