Simple, rapid and precise determination of free sulfuric acid in unstabilized cellulose nitrate is accomplished by dissolving in 90 % v/v acetone–water solution and subsequent titration of sulfate by the
Lead sulfide ore is taken as raw material and subject to reaction with nitric acid under certain conditions to obtain the lead nitrate solution containing Zn2 +, Fe3 +, Cu2 + and other impurities. This solution, through impurity removal, concentration crystallization, can generate lead nitrate....
Though the reaction has been commercialized in a reactive distillation column, it is surprising that a systematic study on the kinetics of this reaction in the presence of sulfuric acid as catalyst is not evident in the open literature. As in the MTBE system, the rate expression in the form ...

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 ...
The dissolution rates of uranium were slow, therefore large doses of chemicals were required (sulfuric acid at about 5% with nitric acid and nitrate as the main oxidants). Starting in 1968, more than 4 million tons of sulfuric acid, 300 000 tons of nitric acid, and 120 000 tons of ...
