This detailed guide explores the chemical's properties, applications, safety measures, and where to buy ammonium chloride 99.5% UK online.
What is Ammonium Chloride?
Ammonium chloride is an inorganic compound formed by the reaction of ammonia (NH3) and hydrochloric acid (HCl). It appears as a white, crystalline powder that is highly soluble in water.
Chemical Formula: NH4Cl
Molar Mass: 53.49 g/mol
Appearance: White, odourless crystalline powder
Solubility in Water: 29.7 g/100 mL (25°C)
Key Uses of Ammonium Chloride 99.5%
Ammonium chloride is widely used due to its effectiveness and versatility. Here are the major applications:
1. Laboratory and Analytical Chemistry
Used as a buffer solution component and reagent in chemical analysis.
-
Example: Preparing a buffer by mixing 50 g of NH4Cl in 1 litre of ammonia solution.
2. Metalwork and Soldering
Acts as flux to clean metal surfaces by removing oxides.
-
Example: 10 g of NH4Cl mixed with 90 g of zinc chloride to create a flux paste.
3. Fertiliser and Agriculture
Used as a nitrogen source in fertilisers, especially in rice and wheat farming.
-
Usage: Apply 200 kg of ammonium chloride per hectare.
4. Textile and Dyeing Industry
Serves as a mordant to fix dyes onto fabrics.
-
Ratio: 25 g per litre of dye bath for cotton fabrics.
5. Batteries
A key ingredient in dry cell batteries (electrolyte component).
6. Cleaning Products
An effective component in cleaning formulations for industrial equipment.
