What are sodium phosphate?


Sodium phosphates are a group of inorganic compounds that contain sodium (Na) and phosphate (PO₄) ions. They are widely used in various industries, including chemicals, detergents, food processing, and water treatment. Sodium phosphates can exist in several forms



Water Treatment: To control corrosion and scale buildup in water systems.
Detergents and Cleaning Products: For removing grease, stains, and dirt.
Food Processing: Used as an emulsifier, acidulant, and sequestrant in some food items.
Chemical Synthesis: Used as a buffer in various chemical reactions.
Agriculture: Fertilizers and soil conditioners may contain sodium phosphates.


Sodium Phosphate Monobasic (NaH₂PO₄): This is a weak acid and is commonly used in buffering solutions in laboratory and industrial processes.

Sodium Phosphate Dibasic (Na₂HPO₄): It is often used in water treatment, as a dispersing agent, and in some cleaning products.

Sodium Phosphate Tribasic (Na₃PO₄): Known as trisodium phosphate (TSP), it is a strong alkaline compound used in cleaning, as a degreasing agent, and in industrial applications like soap manufacturing.

Trisodium Phosphate Dodecahydrate (Na₃PO₄·12H₂O): A crystalline form of TSP with water molecules bound to it, commonly used in industries for its strong alkalinity and as a cleaning agent.
