Sodium sulfide: Density: 1.86 g/cm³: Molecular Weight/ Molar Mass: 78.0452 g/mol: Autoignition temperature > 480 °C (896 °F; 753 K) Melting Point: 1,176° C (2,149° F) Chemical Formula: Na 2 S
5 days ago · 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. If the compound is exposed in the moist air, Na2S and its hydrates emit hydrogen sulfide.
Jun 12, 2014 · The formula for sodium sulfide is Na_2S. Since this is an ionic compound, you must balance the charges so that overall charge of the compound is neutral. Sodium, an alkali metal, has a tendency to lose one electron. As a result sodium normally carries a positive one charge. Sulfur, a nonmetal, has a tendency to gain 2 electrons.
Sodium sulfide. Molecular Formula Na 2 S; Average mass 78.045 Da; Monoisotopic mass 77.951607 Da; ChemSpider ID 14120
Formula and structure: The sodium sulfide formula is Na 2 S 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. The geometry of the structure is a antifluorite, with Na + centres are eight-coordinate, being centered in a "box" for eight ...
Dec 30, 2015 · Since sodium is located in group 1 of the periodic table, it will lose its valence electron and form 1 + cations. As you know, ionic compounds must be neutral. This means that you need two sodium cations to balance the negative charge of the sulfur anion. The ionic formula for sodium sulfide will thus be.
