In the laboratory, the salt can be prepared by reduction of sulfur with sodium in anhydrous ammonia, or by sodium in dry THF with a catalytic amount of naphthalene (forming sodium naphthalenide): [7] 2 Na + S → Na 2 S. Reactions with inorganic reagents.
To prepare 1000 mL of a 0.1 mol/L solution of Sodium sulfide we have to dissolve 7.805 g of Na2S (100 % purity) in deionized or distilled water.
Preparation Method. There are two methods for preparing the sodium sulfide. They are in the carbothermic reactions the sodium sulfate is reacted with the coal at the moderate temperature and it gives the result of sodium sulfide. Carbon dioxide is emitted as the byproduct.
identify the reagents necessary to prepare a given sulfide. write an equation to illustrate the formation of a trialkylsulfonium salt from a sulfide and an alkyl halide.
The production of sodium sulfide requires six essential processes. These processes are vital to manufacturing superior, untainted product. It is generated by interacting carbon or other reducing gases—often coal or coke—with sodium sulfate.
Preparation. Industrially Na 2 S is produced by carbothermic reduction of sodium sulfate often using coal: Na 2 SO 4 + 2 C → Na 2 S + 2 CO 2. In the laboratory, this compound salt can be prepared by reacting elemental sulfur with sodium in anhydrous ammonia, in dry THF with a catalytic amount of naphthalene (forming sodium naphthalenide): 2 ...
ChemSpider record containing structure, synonyms, properties, vendors and database links for Sodium sulfide, 1313-82-2.
Sodium sulfide is a salt which plays an essential role in the organic chemistry industry. The formula for sodium sulfide is Na2S, or more commonly its hydrate Na2S·9H2O. Both the anhydrous and the hydrous salts are colourless solids. Sodium sulfide is a water-soluble compound, with a strongly alkaline solution.
In the laboratory, the salt can be prepared by reduction of sulfur with sodium in anhydrous ammonia, or by sodium in dry THF with a catalytic amount of naphthalene (forming sodium naphthalenide): [7] 2 Na + S → Na 2 S. The sulfide ion in sulfide salts such as sodium sulfide can incorporate a proton into the salt by protonation: S 2− + H ...
