Two of the earliest uses of metallic sodium were in the manufacture of sodium cyanide and sodium peroxide. Significant quantities were used in the manufacture oftetraethyl leadas a gasoline additive, a market that disappeared with the advent of unleaded gasoline. Substantial amounts of sodium are ...
Extracting gold and silver from ores; electroplating baths; case hardening steel by liquid nitriding; manufacture of hydrocyanic acid and other cyanides. Uses Sodium cyanide is used for electroplating metals such as zinc, copper, cadmium, silver, and gold, and their alloys; for extracting gold and...
Hydrogen sulfide actively adds to SNP to form a red violet complex, the basis of the “Gmelin” test of sulfide, and this reaction also facilitates cyanide ion dissociation [46]. A recent reexamination of the H2S/−SH reaction with the metal-coordinated NO of SNP reveals initial addition ...

Both citric and oxalic acids in 5% sulfuric acid solution served as suitable complexing agents. The absence of interelement effects is...
It is used principally in the manufacture of tetraethyl lead (a gasoline antiknock compound) and of sodamide, NaNH2, sodium cyanide, NaCN, sodium peroxide, Na2O2, and sodium hydride, NaH. Sodium compounds are extensively used in industry and for many nonindustrial purposes. Among the most ...
Sodium cyanide solution, from a working production installation which reacts pure 99.5% liquid hydrocyanic acid with NaOH was used in this experiment. The composition of the NaCN solution obtained from the production unit was: SODIUM CYANIDE: 43.75 wt. % ...
