Frequently Asked Questions
What is the primary use of Ammonium Sulfate?
The primary use of Ammonium Sulfate is as an active nutrient component in the manufacturing of commercial ammonium sulfate fertilizer blends. It is additionally deployed in laboratory setups for protein purification via ammonium sulfate precipitation, and acts as an efficient industrial fire retardant intermediate.
What is the molecular weight and chemical formula of Ammonium Sulfate?
The formal ammonium sulfate chemical formula is written as (NH4)2SO4, representing its distinct ionic composition. The compound's structural molar mass or molecular weight is established at approximately 132.14 g/mol.
How is Ammonium Sulfate prepared or synthesized industrially?
Large-scale industrial ammonium sulfate production is carried out by channeling gaseous ammonia through vessels containing hot, concentrated sulfuric acid. It is also efficiently collected as an eco-friendly secondary by-product across caprolactam lines and steel coke oven processes.
What is the Ammonium Sulfate structure and is it an acid or base?
The chemical framework forms an inorganic ionic salt lattice that features a tetrahedral arrangement of two ammonium groups surrounding a divalent sulfate cluster. Chemically, it functions as an acidic salt; dissolving it creates a clear aqueous ammonium sulfate solution displaying an acidic ph value between 5.0 and 6.0.
What is the nitrogen and sulfur nutrient content of Ammonium Sulfate?
Standard high-purity industrial variants hold a stable nitrogen profile. It contains a minimum of 21% ammoniacal nitrogen bound seamlessly with 24% highly soluble sulfur content, making it highly effective for fast plant absorption.
What are the key physical properties, such as boiling point and density?
Key properties include a characteristic clean white color crystalline solid state with a density reading of 1.77 g/mL. Rather than boiling naturally, the ammonium sulfate crystals start to experience thermal decomposition when temperatures cross past 235 C.
How is Ammonium Sulfate used in fertilizer or agrochemicals?
In global agribusiness setups, specialized ammonium sulfate fertilizer uses center around direct soil amendment for alkaline fields. It delivers nitrogen and sulfur directly to roots while lowering overall soil ph levels, boosting plant metabolism and crop outputs compared to standard mixes.
Is Ammonium Sulfate hazardous and what are the handling precautions?
Ammonium Sulfate salt presents minimal industrial handling dangers compared to volatile nitrogen nitrates. However, fine floating airborne ammonium sulfate powder might generate minor skin or respiratory pathway redness. Plant supervisors recommend basic protective gear like filter masks, gloves, and operating in spaces with adequate localized cross ventilation.
What is the common name or trade name for Ammonium Sulfate?
It is commonly traded as diammonium sulfate, sulfuric acid diammonium salt, or sold directly to retail stores as raw crystalline fertilizer. In regional markets, buyers frequently consult catalogs using search phrases like ammonium sulfate ka formula or ammonium sulfate ka sutra.
