Salts are compounds that form when metals react with nonmetals, such as sodium chloride (NaCl). They may also form from cation and anion combinations, such as ammonium nitrate (NH4NO3). Precipitation is both a physical and chemical process, wherein soluble metals and inorganic compounds change ...
The Pb stock solution was prepared by dissolving 1.598 g of lead (II) nitrate (Merck, Germany) in 100 mL of ultrapure water, diluted with deionized water up to 1000 mL. The working solutions (30, 65 and 100 mg/L) were prepared by diluting the stock solution with double distilled water....
The metal is oxidized to PbO when heated with sodium nitrate at elevated temperatures. Pb + NaNO3 → PbO + NaNO2 Lead is widely used in storage batteries. Each cell consists of a spongy lead plate as cathode and lead dioxide as anode immersed in the electrolyte sulfuric acid. The overall ...

planting. Control grains were immersed in sterile distilled water. Lead nitrate solution at concentrations of 200, 600, and 1000 mg per kg of soil was added. The control was kept without adding any lead nitrate solution. Before cultivation, the lead nitrate solution had been applied to the ...
Recently, a Mn(II)/MnO2 positive electrode coupled with a Pb electrode in an acidic H2SO4 electrolyte was developed as a high voltage aqueous battery for large-scale energy storage [186]. This battery is based on the deposition of MnO2 and dissolution of MnO2 into Mn2+ in acidic MnSO4 ...
Changes in the absorption spectra of solutions of compounds 1 and 2 during titration with a solution of bismuth(III) and lead(II) nitrate in a mixture of DMSO:water (1:1, v/v) are shown in Fig. 2. The absorption maxima for 1 and 2 are located at 502 nm and 516 nm, ...
The electrochemical variables including pH of the solution, amount of Ti3C2/Fe3O4/g-C3N4 on the GCE surface, supporting electrolyte and deposition time were optimized to get maximum sensitivity. Under optimal conditions, Ti3C2(HF)/Fe3O4/g-C3N4 sensor exhibited excellent performance for Zn (II...
