Sodium sulfide is the chemical compound with the formula Na2S, or more commonly its hydrate Na2S·9H2O. Both are colorless water-soluble salts that give strongly alkaline solutions. When exposed to moist air, Na2S and its hydrates emit hydrogen sulfide, which smells like rotten eggs.

Then, what is the formula for sodium sulfide?
Beside above, what is the net charge of sodium sulfide? Combine these two ions so that the total charge is zero. In this case, it take two 1+ charges per one 2- charge. Thus the formula for sodium sulfide is Na2S.
In respect to this, what is sodium sulfide used for?
Sodium sulfide is used in the pulp and paper industry, water treatment, textile industry, and various chemical manufacturing processes including the production of rubber chemicals, sulfur dyes and oil recovery. Along with its hydrate form, sodium sulfide releases hydrogen sulfide (H2S) when in contact with moist air.

Is sodium sulfide dangerous?
Safety. Like sodium hydroxide, sodium sulfide is strongly alkaline and can cause skin burns. Acids react with it to rapidly produce hydrogen sulfide, which is highly toxic.
Is sulfur and sodium the same?
If you look at a periodic table, sodium appears on the left side in the group known as alkali metals, while sulfur appears on the right side in the group known as non-metals.
Is sodium a metal?
Sodium is an element that is a member of the alkali metal group with a symbol Na. It is physically silver colored and is a soft metal of low density. Pure sodium is not found naturally on earth because it is a highly reactive metal.
How do you make sodium sulfide solution?
Preparation of sodium sulfide Hydrogen sulfide is passed through 3 parts of concentrated sodium hydroxide solution until no further absorption takes place. Then 2 parts of concentrated sodium hydroxide solution is added in order to neutralize sodium hydrosulfide.
How do you name Na2S?
It is a sulfide salt and an inorganic sodium salt. Sodium sulfide is a chemical compound with a chemical formula Na2S.
How do you write chemical formulas?
Part 1 Writing Chemical Formulas of Covalent Compounds Memorize the prefixes for number of atoms. Write the chemical symbol for the first element. Add the number of atoms as a subscript. Write the chemical symbol for the second element. Add the number of atoms present as a subscript. Practice with some examples.
Is sodium sulfide an electrolyte?
Yes it is. Sodium Sulfate Anhydrous is the anhydrous, sodium salt form of sulfuric acid. Sodium sulfate anhydrous is an electrolyte replenisher and is used in isosmotic solutions so that administration does not disturb normal electrolyte balance and does not lead to absorption or excretion of water and ions.
What is the role of sodium sulfate?
Sodium sulfate is mainly used for the manufacture of detergents and in the Kraft process of paper pulping, although it has many other uses. About half of the world”s production is from the natural mineral form of the decahydrate (mirabilite), and half from by-products of chemical processes.
What is the pH of sodium sulfide?
Sodium Hydrosulfide It is prepared by absorption of hydrogen sulfide in sodium hydroxide. It is shipped as a 45% solution with a specific gravity of 1.303 and a pH of 10.4. The viscosity is 7 centipoise. The solution tends to crystallize below 62°F (17°C).
Is sodium sulfide a cation or anion?
Explanation: When dealing with ionic compounds, it”s important to know that the cation is always written first and the anion is written second. In this case, sodium, Na , will be your cations and sulfide will be your anion.
Is sodium sulfide soluble in water?
Its density is 2.427. It will be subject to decomposition at 920 ℃. It is soluble in cool water and easily soluble in hot water with dissolving in water almost fully being hydrolyzed into sodium hydroxide and sodium hydrosulfide (at 10 ℃, the solubility is 15.4; while the solubility is 57.2 g at 90 ℃).
How do you dispose of sodium sulfide?
1. All waste of sodium sulfide must be collected in a sealable compatible container (i.e. brown glass bottle) and disposed as hazardous waste as per University Hazardous Waste Guidelines. 2. All residual materials and rinse water from empty containers of this material must be collected and disposed as hazardous waste.
Is Na2S an acid or base?
Na2S is a salt of a weak acid (H2S) and a strong base (NaOH). An aqueous solution of such a salt is distinctly basic owing to the presence of additional OH- ions that are produced by hydrolysis of the anion. So, Na2S is also a basic salt like Na2CO3, CaCO3, CH3COONa etc.
