Ammonium Thiosulfate solution:
This compound dissolves well in water and has a much higher solubility than its salt-like potassium persulfate. Dissolving this salt in water is an endothermic process.
Ammonium Thiosulfate production process:
This is an inorganic solution produced by treating ammonium sulfite with sulfur:
(NH4)2SO3 + S → (NH4)2S2O3
This solution can also be produced by mixing two solutions of ammonium sulfate and sodium thiosulfate and then cooling and filtering sodium sulfate.
Ammonium Thiosulfate Uses:
Fertilizer:
The primary use of ammonium sulfate is as an agricultural fertilizer for alkaline soils.
Medical:
Due to its antibacterial properties, this compound is used in the medical industry to produce vaccines (tetanus, diphtheria, etc.).
Photography:
this material is also used to repair negatives and help their emergence.
Food:
Ammonium thiosulfate can be used as yeast in baking bread.
Other uses:
- This compound is also used in gold and silver mines to leach and remove impurities.
- This product reduces the combustion temperature, so it can be used to control the flame.
Ammonium Thiosulfate Fertilizer:
Perhaps the most important application of this substance can be considered as agricultural fertilizer, fertilizer containing this substance can be a good source of nitrogen and sulfur needed by the plant for growth, liquid ammonium thiosulfate fertilizer, which is obtained by dissolving the product in water For crops such as corn and soybeans that require sulfur and nitrogen, it has a much better performance than other sulfur fertilizers. Sulfur plays an important role in protein synthesis and has a disinfectant role while increasing nitrogen efficiency. like Ammonium persulfate, It should not be forgotten that using it in large quantities may burn the roots of the plant.
