What is Sodium Dihydrogen Phosphate?

Sodium Dihydrogen Phosphate, which is also referred to as monobasic sodium phosphate or sodium dihydrogen phosphate, is an inorganic compound consisting of sodium combined with a dihydrogen phosphate (H2PO4−) anion. It is classified as one of the sodium phosphates and is widely used in various industrial applications. This chemical compound is available in different forms, including an anhydrous form, as well as mono- and dihydrates.

Monosodium phosphate formula (NaH₂PO₄) can be synthesized by combining phosphoric acid and sodium chloride. This process takes advantage of the fact that an organic solution containing an amine can extract the components of hydrochloric acid (HCl). Amines exhibit a higher selectivity towards hydrochloric acid compared to phosphoric acid. As a result, the sulphate component remains in the organic phase. To retrieve monosodium phosphate, the organic phase can be stripped by using a sodium chloride solution. This process separates the organic compounds, allowing for the recovery of monosodium phosphate.

Properties of Sodium Dihydrogen Phosphate

Sodium dihydrogen phosphate, also known as monosodium phosphate or sodium phosphate monobasic, is a chemical compound with the formula NaH2PO4. It is a crystalline solid commonly used in various applications due to its versatile properties. Here are some key properties of sodium dihydrogen phosphate:

Chemical Formula

The chemical formula of sodium dihydrogen phosphate is NaH2PO4. It indicates that each molecule of sodium dihydrogen phosphate consists of one sodium (Na) atom, two hydrogen (H) atoms, one phosphorus (P) atom, and four oxygen (O) atoms.


Sodium dihydrogen phosphate is highly soluble in water. When mixed with water, it readily dissociates into sodium ions (Na+) and dihydrogen phosphate ions (H2PO4-). This high solubility makes it suitable for various applications where a water-soluble compound is required.


 Sodium dihydrogen phosphate is an acidic compound. When dissolved in water, it releases hydrogen ions (H+) and acts as a weak acid, resulting in a slightly acidic solution. The pH of a sodium dihydrogen phosphate solution is typically around 4.5.

Crystalline Structure

Sodium dihydrogen phosphate forms crystals with a monoclinic structure. The crystals are usually white or colourless and have a characteristic shape.

Buffering Capacity

 Sodium dihydrogen phosphate is commonly used as a buffering agent in various chemical and biological applications. It can help maintain a stable pH in solutions by acting as both an acid and a base, depending on the conditions.

Food Additive

Sodium dihydrogen phosphate is approved by regulatory authorities as a food additive and is used in the food industry. It can act as an acidity regulator, emulsifier, and sequestrant in various food products.

Safety Considerations

 While sodium dihydrogen phosphate is generally considered safe when used in appropriate concentrations and applications, it is important to handle it with care. Like other chemicals, it should be stored, handled, and disposed of according to proper safety guidelines.

Sodium Dihydrogen Phosphate Applications

Sodium dihydrogen phosphate, also known as monosodium phosphate or sodium phosphate monobasic, has numerous applications across various industries. Here are some common applications of sodium dihydrogen phosphate:

  1. Food Industry: Sodium dihydrogen phosphate is widely used as a food additive in the food industry. It serves as an acidity regulator, helping to adjust the pH levels in food products. It is used in beverages, dairy products, baked goods, canned foods, and processed meats.
  2. Water Treatment: Sodium dihydrogen phosphate is utilized in water treatment processes. It acts as a buffering agent to control and stabilize the pH of water in various applications, such as swimming pools, aquariums, and industrial water systems.
  3. Pharmaceuticals: In the pharmaceutical industry, sodium dihydrogen phosphate is used as a component in the formulation of drugs and medications. It can be employed as a buffering agent to maintain the desired pH levels in pharmaceutical preparations.
  4. Detergents and Cleaning Products: Sodium dihydrogen phosphate is an effective cleaning agent and is used in the formulation of detergents and cleaning products. It helps in removing stains and dirt from various surfaces.
  5. Agriculture: Sodium dihydrogen phosphate is utilized in agriculture as a source of phosphorus, an essential nutrient for plant growth. It can be applied as a fertilizer to promote healthy root development and overall plant growth.
  6. Electroplating: Sodium dihydrogen phosphate is employed in electroplating processes as a pH buffer. It helps maintain a stable pH environment during the electroplating of metals, ensuring efficient and uniform metal deposition.
  7. Laboratory Applications: Sodium dihydrogen phosphate finds applications in laboratory settings as a chemical reagent. It can be used in various analytical and research procedures, such as buffer preparation, pH adjustment, and as a component in biochemical assays.
  8. Fire Retardants: Sodium dihydrogen phosphate is utilized as a fire retardant in certain applications. It can be incorporated into fire-resistant materials, coatings, and paints to enhance their fire resistance properties.

These are some of the common applications of sodium dihydrogen phosphate. Its versatile properties make it valuable in a range of industries, including food, water treatment, pharmaceuticals, agriculture, and more.
