Chemical Name: Phosphoric Acid- H3PO4
Properties:
Phosphoric acid is an important chemical, which finds a multitude of uses in agriculture, medicine and many different industries.
Phosphoric acid, also known as orthophosphoric acid, is one of the most widely known and used acids. It is a mineral acid that contains three atoms of hydrogen, one atom of phosphorus, and four atoms of oxygen. Thus, the chemical formula of phosphoric acid is H3PO4. This is an important acid which has a wide range of uses and different P2O5 content. Among many applications, the most uses of phosphoric acid are as below.

Removal of Rust:
One of the most common uses of phosphoric acid is for the removal of rust from metal surfaces. It acts as a rust converter on direct application to rusted iron, steel, and other metal surfaces. It converts reddish-brown iron, that is, ferric oxide, to black-colored ferric phosphate. After this treatment, the black ferric phosphate coating can be easily scrubbed off, revealing the underlying fresh metal surface.
Use in Processed Food:
Phosphoric acid is used as an additive to acidify foods and beverages, like the various colas. It provides a tangy or sour taste, and as it is mass produced, this chemical is quite easily available.
Medical Uses:
One of its important uses is in the fields of medicine and dentistry. Phosphoric acid is used as an ingredient in over-the-counter anti-nausea medications, which also happen to contain high levels of sugar, that is, glucose and fructose. In dentistry, this acid is combined with zinc powder to form zinc phosphate, which is used as a temporary dental cement. It is also used in orthodontics as an etching solution, so as to clean and roughen the surface of teeth before the placement of brackets and other dental appliances. This acid is also used in many teeth whitening solutions to eliminate plaque that may be present on the surface of the teeth.
Other Uses:
It is used as an electrolyte in phosphoric acid fuel cells. It is also used as a cleaner in construction-related trades, so as to remove mineral deposits, cement smears, and hard water stains. Hot phosphoric acid is used in micro-fabrication to etch silicon nitride. It is used as a flux by hobbyists to aid in the process of soldering. It is also used in hydroponics pH solutions to lower the pH of nutrient solutions.
Phosphoric acid is also used as an electrolyte in copper electro-polishing for burr removal. In compound semiconductor processing, it is a commonly used as a wet etching agent. This acid is used as a pH adjuster in cosmetics and other skin care products. It is also used as a chemical oxidizing agent for activated carbon productions. It is used with distilled water as an electrolyte in oxyhydrogen generators. Thus, phosphoric acid is an important acid which has several different applications in various industries such as phosphating of metals and wide range from metallurgy to the food industry. It is one of the most important and useful acid that have strong power and low danger.
Packing:
35 kg plastic drums or in IBC (1000 lit container) as per request.
Storage and Handling:
Keep in a tightly closed container. Store in a cool, dry, ventilated area away from sources of heat, moisture and direct sunlight. Corrosive to mild steel. Store in rubber lined or 316 stainless steel designed for phosphoric acid. Do not wash out container and use it for other purposes. When diluting, the acid should always be added slowly to water and in small amounts. Never use hot water and never add water to the acid. Water added to acid can cause uncontrolled boiling and splashing. Protect from freezing.
