What is the molar mass of sodium sulfide?
Formula and structure: The sodium sulfide formula is Na2S the molar mass is 78.0452 g mol-1. The salt also has a hydrated form 240.18 g mol-1 The molecule is formed by two sodium cations Na+ and one sulfur anion -2.
Is sodium sulfate an aqueous or a solid?
Sodium sulfate is an important compound of sodium. When anhydrous, it is a white crystalline solid of formula Na2SO4. The deca hydrate, Na2SO4•10H2O, is known as Glauber's salt. Sodium sulfate is mainly used for the manufacture of detergents and in the Kraft process of paper pulping, although it has many other uses.

What is the formula for sodium sulfide?
The industrial sodium sulfide is mostly a mixture with different numbers of crystalline water. Hence the molecular formula of sodium sulphide is Na2S • nH2O. This sodium sulfide exhibits as yellow or in reddish-brown colour, and it is flaky and granular. It is mainly used in paper, dyes, ore floatation, mineral processing, dyeing industries and printing.
What is sodium sulfide used for?
Sodium sulfide is mainly used in the pulp and paper industry for the kraft process. As in the kraft process, wood is converted into wood pulp, sodium hydroxide and sodium sulfide help to dissolve the lignin of wood fibre.
Is sodium sulfide flammable?
Sodium sulfide is strongly alkaline. It can cause significant skin burns. Reacting with acid can form hydrogen sulfide, which is a highly toxic and flammable gas. In reduced ventilation spaces, hydrogen sulfide accumulates at the bottom. To use hydrogen sulfide, one should keep the safety data sheet with them.
Is sodium sulfide soluble in water?
Sodium sulfide is slightly soluble in alcohol but insoluble in ethers, although the solubility of sodium sulfide depends on the temperature as it is highly soluble. Another main reason behind the solubility of sodium sulfide in water is, it is an ionic compound which tends to disassociate its ions in water.

Overview
Sodium sulfide is the chemical compound with the formula Na2S, or more commonly its hydrate Na2S·9H2O. Both the anhydrous and the hydrated salts are colorless solids. They are water-soluble, giving strongly alkaline solutions. When exposed to moist air, Na2S and its hydrates emit hydrogen sulfide, an extremely toxic, flammable and corrosive gas which smells like rotten eggs.
Structure
Na2S adopts the antifluorite structure, which means that the Na centers occupy sites of the fluoride in the CaF2 framework, and the larger S occupy the sites for Ca .
Production
Industrially Na2S is produced by carbothermic reduction of sodium sulfate often using coal:
Na2SO4 + 2 C → Na2S + 2 CO2
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):
2 Na + S → Na2S
Reactions with inorganic reagents
The sulfide ion in sulfide salts such as sodium sulfide can incorporate a proton into the salt by protonation:
S + H → SH
Because of this capture of the proton ( H ), sodium sulfide has basic character. Sodium sulfide is strongly basic, able to absorb two protons. Its conjugate acid is sodium hydrosulfide (SH ). An aqu…
Uses
Sodium sulfide is primarily used in the kraft process in the pulp and paper industry.
It is used in water treatment as an oxygen scavenger agent and also as a metals precipitant; in chemical photography for toning black and white photographs; in the textile industry as a bleaching agent, for desulfurising and as a dechlorinating agent; and in the leather trade for the sulfitisation of tanning extracts. It is used in chemical manufacturing as a sulfonation and sulfo…
Safety
Like sodium hydroxide, sodium sulfide is strongly alkaline and can cause chemical burns. Acids react with it to rapidly produce hydrogen sulfide, which is highly toxic.
