As an extension of the investigations previously published on the vapour pressures of aqueous solutions saturated with one or two of the salts NH4NO3, NaNO3 and Pb(NO3)2, the vapour pressure of the five phase equilibrium solid NH4NO3solid NaNO3solid Pb(NO3)2saturated solution-water vapour has ...
Pb2+(aq) + 2NO3-(aq) + 2Na+(aq) + S2-(aq) = PbS(s) + 2Na+(aq) + 2NO3-(aq) Spectator Ions Spectator ions are ions that do not take part in the reaction. They are removed from the complete ionic equation to get the net ionic equation. NO3- Na+ ...
Pb(NO3)2 + K2CrO4 = K(NO3) + Pb(CrO4) is a Double Displacement (Metathesis) reaction where one mole of aqueous Lead(Ii) Nitrate [Pb(NO3)2] and one mole of aqueous Potassium Chromate [K2CrO4] react to form two moles of aqueous Potassium Nitrate [K(NO3)] and one mol...
We quantitatively exchanged the interlamellar nitrate groups of Pb3F5NO3 for dichromate, under ambient aqueous conditions. Nuclear magnetic resonance and UV−vis spectroscopy show the reaction proceeds to 61.0% completion in several days. The material is also stable to 450 °C, which is vastly ...
In addition, the ecotoxicity of Pb also depends on the accompanying anions (Cl, SO42–, NO3, etc.) and aging time. Generally, it is necessary to obtain a series of different concentrations of contaminated soil by the addition of soluble metal salts for the dose-response curve fitting (Jiang...
Fabrication of Pt nanoparticles using an amphiphilic copolymer template in aqueous solution was achieved via polybutadiene-block-polyethyleneoxide copolymer micelles, which acted as nanoreactors. In addition, Pt nanoparticles were synthesized using hydrogen gas as the reducing agent in solid state for the...
