Product Overview & Quality

Product Name: Ammonium chloride (Sal ammoniac)
Brand: Kemaus (Product Code: KA-032)
Grade: Laboratory Grade (Lab Grade) featuring a high purity of 99.5 percent or higher. Produced under Kemaus standard laboratory quality control to guarantee exceptional physical uniformity and low trace chemical background. Excellently suited for academic science laboratories, basic chemical titrations, buffer preparations, and industrial chemical formulations.
Physical Properties: Odorless, fine white crystalline powder with a sharp, cooling, salty taste.
Solubility & Thermal Nature: Highly soluble in water (solubility increases substantially in hot water); soluble in alcohol. Dissolution in water is highly endothermic (absorbs significant thermal energy), causing a rapid and noticeable drop in solution temperature. Yields a mildly acidic aqueous solution.
Key Use: Heavily utilized as a core compound paired with aqueous ammonia for preparing standard Ammonia Buffer Solutions in analytical chemistry. These buffers are essential for maintaining stable alkaline backgrounds (typically within the pH 9 to 10 window), commonly required in complexometric water hardness titrations. Used as an analytical reagent in qualitative ionic separation schemes, and functions as a basic reactant in school laboratories for demonstrating endothermic dissolution phenomena and flame test behaviors.

Safety & Hazards (Critical)

Classification: Harmful if swallowed. Causes serious eye irritation.
Health Risks: Direct eye contact triggers immediate stinging irritation, watering, and temporary redness due to its mildly acidic salt profile. Prolonged or repeated skin exposure may cause minor localized dryness or irritation. Inhalation of fine airborne dust particles irritates the upper respiratory tract, inducing coughing or sneezing.
First Aid Measures: Flush affected eyes or skin immediately with plenty of flowing water for at least 15 minutes. If swallowed, rinse mouth thoroughly with water and seek medical attention.

Handling & Storage

Storage: Hygroscopic material. It can absorb ambient moisture from the surrounding air, leading to physical caking or severe clumping. Must be stored in its original, tightly sealed Kemaus container. Keep in a cool, dry, and well-ventilated dedicated chemical safety space at stable room temperature (below 30 degrees Celsius). Keep strictly separated from strong acids, strong oxidizing agents, and strong bases (as reaction with strong bases will immediately liberate volatile, pungent ammonia gas).
Precautions: Wear standard personal protective equipment (PPE), including laboratory chemical gloves, safety glasses, and a particulate dust mask. Ensure the container cap is secured tightly immediately after each use.
