Phosphoric Acid

Phosphoric Acid

With the chemical formula H3PO4, phosphoric acid is an inorganic, colorless, and odorless substance. A common ingredient in fertilizers, it is a significant industrial chemical. Take away all three H+ ions and it forms esters known as organophosphates. Aside from being an external standard for phosphorus-NMR, phosphoric acid is also used as an anti-rust treatment and to stop iron oxidation. Chemical metal polishing, microfabrication, skincare, dairy, food, and compound semiconductor manufacturing are some of the other sectors that employ it.

FAQs - Phosphoric Acid

How come H3PO4 is known as orthophosphoric acid?
The prefix ortho sets orthophosphoric acid apart from polyphosphoric acids, which are other forms of phosphoric acid.
Why do soft drinks contain phosphoric acid?
Acids neutralize the sweetness of sugar in drinks; phosphoric acid, for example, is added to cola drinks to improve tartness, reduce bacteria, and extend shelf life.
Is phosphoric acid a strong acid?
Phosphoric acid is a weak acid compared to some other mineral acids like sulfuric acid or hydrochloric acid. It partially dissociates in water, releasing hydrogen ions and forming hydrogen phosphate ions.
How is phosphoric acid produced?
Phosphoric acid is typically produced through the wet process, which involves treating phosphate rock with sulfuric acid. This reaction produces phosphoric acid along with other byproducts, which are then further processed to obtain the desired concentration and purity of phosphoric acid.
What are the different concentrations of phosphoric acid available?
Phosphoric acid is available in various concentrations, typically ranging from around 10% to 85% concentration by weight. The concentration of phosphoric acid determines its strength and suitability for different applications.

Soda Ash

Soda Ash

Two industries dominate global soda ash demand: glass manufacturing and detergents. They use the same chemical compound, sodium carbonate, but in physically different forms. Glass plants need dense soda ash for the free-flowing batch handling their furnaces require. Detergent makers need light soda ash that dissolves rapidly into formulation. Buying the wrong grade creates real operational problems downstream, which is why grade selection is the first procurement decision soda ash buyers actually make. Elchemy supplies ELRASA™-SAL Soda Ash in both dense and light grades to industrial buyers across 40+ countries, with quality matched to glass-grade, detergent-grade, and chemical-processing-grade specifications. Domestic stock is also held at our US warehouses for faster fulfillment.

Caustic Soda Flakes

Caustic Soda Flakes

Caustic soda flakes, also known as sodium hydroxide flakes, are a solid form of caustic soda (NaOH) that appear white and crystalline. Highly soluble in water, these flakes produce a strong alkaline solution. As one of the most potent alkalis, caustic soda is extremely corrosive and widely recognized for its versatility across industrial sectors. It remains one of the most essential chemical compounds produced and supplied by leading caustic soda producers worldwide.
