Applications of Phosphoric Acid in Various Industries

Applications of Phosphoric Acid in Various Industries

08 August 2022

Fertilizer production relies heavily on phosphoric acid (H3PO4), making it one of the most often used acids. There are several uses for phosphates, which are the salts of this acid. This is a word that chemistry students may come across on a regular basis. To place an order for Phosphoric acid for your science lab in your school or educational institute in Sharjah, Palvi FZE is one of the most affordable as well as distinct Phosphoric Acid suppliers in Sharjah.



Weak acids, such as phosphoric acid, are acidic in nature. In order to differentiate it from various types of phosphoric acids like polyphosphoric acid, it is sometimes known as orthophosphoric acid. Phosphoric(V) acid is a different name for this acidic substance. This acid is solid at room temperature as well as non-toxic in its pure form. In terms of molecular weight, it weighs 97.99 g/mol.



The mineral acid H3PO4 is considered one of the most helpful as well as essential. The acid is a colourless, odourless, and nonvolatile liquid that is most commonly found as an aqueous solution. In spite of being a "weak acid," the solution is a viscous and sticky liquid that can irritate or burn your skin and harm your eyes and your nasal membranes.


Physical Properties listed by one of the top ranking Phosphoric Acid exporters in Sharjah:


  • Solid white crystals
  • Melting Point 42.4°C.
  • Colourless, Odourless and Viscous acid.
  • Non-toxic and Stable.

Chemical Properties:


  • As many as three H+ ions can be liberated by phosphoric acid, which is H3PO4. As compared to various mineral acids, Phosphoric acid has a unique reaction.
  • When reacting with bases, three types of salts are often formed.
  • Meta-phosphoric, as well as Polyphosphoric acids, produce dimers, trimers, and even lengthy polymeric chains when phosphoric acid molecules are heated to high temperatures.

Applications of Phosphoric Acid in Various Industries:


 - Agriculture:


Fertilizers account for the majority of the phosphoric acid generated. It is primarily transformed into fertilizer-grade triphosphate salts such as,



  • Triple superphosphate (TSP)
  • Diammonium hydrogen phosphate (DAP)
  • Monoammonium dihydrogen phosphate (MAP)
  • Phosphoric acid is also included as a feed additive for livestock, swine, and poultry.

- Food additives:


The acidic taste of phosphoric acid can be enjoyed in diluted solutions. As a result, it's found in foods as an additive. Because of this, it gives off an acidic smell to


  • Soft drinks.
  • Other readymade foods.
  • Water treatment products.



Manufacturing process:


Phosphoric acid is used to manufacture


  • Gelatin.
  • Soil stabilizer.
  • Waxes and polishes.
  • Binder for ceramics.
  • Activated carbon.
  • In lakes in cotton dyeing.



 - Medical applications:


  • In dental cement.
  • In Preparation of albumin derivatives.
  • To acidify the urine.
  • To remove necrotic debris.
  • In anti-nausea pills.
  • In mouth washing liquid as well as teeth whiteners.


 -Personal care:


The following personal care products would not be possible without phosphoric acid:


  • Cleansing products
  • Bath products
  • Fragrances
  • Haircare products
  • Nail products
  • Makeup
  • Skincare products


 - Rust removal:


Rust can be removed with phosphoric acid. Phosphoric acid reacts with rust on metals like steel and iron when applied to the rust. Afterwards, the rust is transformed into a black-coloured compound that may be easily removed from the surface. If you are looking for an excellent Phosphoric Acid distributor in Sharjah, Palvi FZE is the best pick for you who can fulfil all of your rust removal as well as industrial chemical needs.
