Ammonium Sulfide Formula, Molar Mass, and Solution

Ammonium sulfide is an inorganic compound that consists of nitrogen, sulfur, and hydrogen. It emits a pungent odor similar to rotten eggs and can be found in the form of a light yellow liquid or crystalline solid.

Ammonium sulfide is a type of inorganic salt that is made up of an ammonium cation (NH4+) and a sulfide anion (S2-). The molecular formula for ammonium sulfide is (NH4)2S.

Ammonium sulfide is produced in the laboratory by reacting ammonium hydroxide with hydrogen sulfide gas, and industrial production involves treating ammonium sulfate with hydrogen sulfide.

Ammonium Sulfide: Its Formula, Molar Mass, and Solution

Properties Of Ammonium Sulfide 

1. Molecular weight is 68.15 g/mol

2. It is a white or pale yellow crystalline solid and liquid.

3. Hydrogen sulfide present in ammonium sulfide gives it a pungent odor of rotten eggs.

4. It is easily soluble in water, alcohol, and ether.

5. Ammonium sulfide, which dissolves in water, has a pH 9-10 and is a weak base.

6. It can react with metal ions to form metal sulfides. It is also reactive with acids and can release hydrogen sulfide gas.

7. Density is 1.17 g/cm3.

8. Ammonium sulfide is a dangerous chemical compound that has caused respiratory problems, skin irritation, and eye damage. It also produces toxic gases such as ammonia and hydrogen sulfide, which can be fatal in high concentrations.

Molar Mass Of Ammonium Sulfide

The molar mass of ammonium sulfide is calculated by adding the atomic masses of all the atoms in a mole of the compound.

On finding out the atomic masses of the elements in ammonium sulfide (NH4)2S).

Nitrogen (N): 14.01 g/mol

Hydrogen (H): 1.01 g/mol

Sulfur (S): 32.06 g/mol

The molar mass of (NH4)2S can then be calculated as:

Molar mass of (NH4)2S = (2 x 14.01 g/mol) + (8 x 1.01 g/mol) + (1 x 32.06 g/mol)

= 56.06 g/mol + 8.08 g/mol + 32.06 g/mol

= 96.2 g/mol

The molar mass of ammonium sulfide (NH4)2S is 96.2 g/mol.

Preparation of Ammonium Sulfide Solutions 

Take 150 ml conc.NH4OH and saturate it with H2S keeping the solution cool. 

It contains 250 ml of concentrate. NH4OH and 10 gm powdered sulfur. 

The mixture is stirred until the sulfur dissolves and is diluted with water to 1 liter. 

In solution, the concentrations of (NH4)2S2, (NH4)2S, and NH4OH are normally 0.625, 0.4, and 1.5, respectively. 

On standing in the ammonium Sulfide Solution, the concentration of (NH4)2S2 increases, and that of (NH4)2S and NH4OH decreases.

Ammonium sulfide uses

Ammonium sulfide is a chemical compound with important industrial and laboratory uses.

1. This reduction is used in photographic processing to develop black-and-white negatives.

2. In analytical chemistry, it is used as a reagent in tests.

3. It is used in the tanning industry as a source of sulfide ions to remove hair and other proteins from animal hides.

4. In the mining industry, it is used to extract metals such as copper, nickel, and zinc from ores.

5. It is used as a fertilizer in agriculture.
