What is Phosphoric Acid Used for?
Phosphoric acid is a commonly utilized acid which is inorganic in form and finds application across a diverse range of industries. Also known by the name orthophosphoric acid, this chemical is used extensively within the food industry. However, its usage is not restricted to this sector alone. This chemical plays an essential role across a range of industrial processes in addition to being a vital element in medical applications, the agricultural domain, and more. In this article we will explore what phosphoric acid is used for, and the critical role it plays in every industry.
Structure of Phosphoric Acid
Phosphoric acid is generally recognized as a dense liquid. This is the most common form in which it is found, and in this form, the acidity of phosphoric acid is a weak acid. Phosphoric acid is a triprotic acid. Although it is more potent and strong than some other acids like lactic and citric acids, it is weaker than the sulphuric and hydrochloric acid varieties. The high phosphoric acid boiling point and stable phosphoric acid molar mass offer it the unique character of being useful for a wide array of applications.

Uses of Phosphoric Acid
In this portion we will explore some of the key industries where phosphoric acid is utilized extensively, highlighting its role in each of them.
Phosphoric Acid Uses in Food Industry
Within the food industry, food grade phosphoric acid performs a range of critical tasks for a variety of food items. This is because it possesses the ability to balance the pH levels of different things to which it is added in addition to performing other tasks.
- As An Acidifier: One of the key roles that phosphoric acid performs is that it acts as an acidifier. In this capacity, it is added extensively in a range of distinct beverages as well as foods to which it adds a mildly tangy and sour taste comparable to what citric acid would do. Phosphoric acid in soft drinks as well as other beverages performs this function.
- As A Yeast Nutrient: Another key function that phosphoric acid performs in the food industry is acting as a nutrient that helps yeast thrive during the process of fermentation. In this capacity, phosphoric acid becomes a critical ingredient in functions like brewing or baking where the activity of yeast directly impacts the overall texture, and flavor of food.
- Antimicrobial Properties: Yet another key function performed by phosphoric acid in food is to disinfect foods and maintain their level of hygiene. Since phosphoric acid has an innate capability of preventing disease-causing bacteria from growing it plays a vital role in dairy production and brewing, making the end products of a much higher quality and more stable and safe for storage and consumption.
- For Blending Oils: A lesser-known use of 85 phosphoric acid in the food industry is its ability to act as a powerful blending agent. In this function, phosphoric acid is a key element in the oil refining process since it helps in removing all of the impurities that may be contained in the oil and allows it to become a more stable, balanced, and refined product which is of a higher quality and can remain shelves table for a long time.
- Improving Flour: For baked goods phosphoric acid uses include not only its functionality as a yeast nutrient but also as an enhancer of the quality of the flour that is being used to create the goods. In this capacity, phosphoric acid acts as a pH balancing agent which directly impacts the consistency and texture of the dough. In addition to this, it helps in enhancing the strength of the gluten which directly impacts the volume and the texture of the end product.
- The Sugar Industry: Within the sugar industry phosphoric acid is used during the process of producing sugar to rid the sugar syrup or juice from any kinds of impurities or unwanted particles which can hamper the quality of the product.
Apart from these food phosphoric acid uses there are also other usages for which this chemical is actively employed within the food industry. These include users like the production of capsules as well as food grade gelatin.
Phosphoric Acid Used in Medical Industry
Within the medical industry, particularly pharmaceuticals phosphoric acid application extends to several uses such as the production of several medicines as well as medical products. For instance, phosphoric acid is used extensively in dental processes in which it is used as an etching solution to clean teeth and prepare them for the process of bonding in which fillings, crowns, as well as other restorative materials are used.
Phosphoric Acid Used for Across Diverse Industries
When it comes to use in industry phosphoric acid performs a range of distinctive functions across diverse industries whether it is manufacturing, metal surface treatment, textile industry, cleaning agents, refractories, or others.
Phosphoric Acid Used for Treating Metal Surfaces
Metal surfaces are susceptible to corrosion when not cleaned or treated properly. Phosphoric acid rust remover is used to treat metal surfaces to prevent them from corroding. In this segment, phosphoric acid is used to create very thin films of insoluble phosphate on the surfaces particularly in the aerospace and automotive sectors before the parts can be painted or coated to minimize the risk of corrosion.
Phosphoric Acid Used for Textile Sector
Within the textile sector, phosphoric acid performs the role of a mordant, which is a critical element in ensuring that the dies and colors used for coloring as well as printing on the fabrics are fixed. Phosphoric acid used for this purpose performs a critical role in ensuring that the colors do not leech or fade for a very long time, thereby guaranteeing that the clothes and fabrics keep looking vibrant and fresh for years. It also helps improve the texture of the fabric and adds shine to it.
Phosphoric Acid Used for Cleaning Agents
Whether it is household cleaners or industrial cleaning agents, phosphoric acid forms a critical component in different kinds of cleaners such as detergents because it acts as a buffering and cleaning chemical. Phosphoric acid helps in easily getting rid of stubborn stains as well as dirt from different kinds of surfaces which makes it a highly useful additive in these products.
Phosphoric Acid Used for Paints And Coatings
Paints and coatings are also important products which benefit from phosphoric acid. In this industry, phosphoric acid is added to boost the properties of rust prevention in the paints or coating materials. Moreover, it also helps in making them resistant to corrosion as well as resistant to radiation which ensures that the surfaces to which it is applied also benefit from these properties. In addition to these properties, phosphoric acid’s properties as an antibacterial agent make it useful for usage in diverse applications and products that are used in harsh environments such as those used in active industries.
Phosphoric Acid Uses in Agriculture
An overlapping use of phosphoric acid which is beneficial for both the agricultural sector as well as for the manufacturing sector is its ability to create phosphates which are a key component in the creation of fertilizers. Phosphoric acid is used in the manufacturing process of phosphates such as ammonium phosphate among others, which play a vital role in a range of industries such as the agricultural sector. The fertilizers which contain ammonium phosphate play a vital role in agricultural advancement because these offer phosphorus to the crops which helps in the process of photosynthesis along with energy transferring and the development of roots in various plants.
