The key breakthrough came in the early 20th century with the invention of the Ostwald process by Wilhelm Ostwald. This process enabled large-scale production of nitric acid and revolutionized its application in modern industries.
This discovery not only changed the course of chemistry but also had lasting effects on various sectors, from agriculture to military technology.
The story of nitric acid begins with ancient alchemists, who played a crucial role in its discovery. Around 800 AD, the Persian scholar Jabir ibn Hayyan (known as Geber in the West) is often credited with first documenting the creation of nitric acid. Geber's work laid the foundation for much of early chemistry.
He used potassium nitrate (also known as saltpeter) and sulfuric acid (vitriol) in his alchemical experiments. By combining these two substances, he was able to produce nitric acid, which alchemists valued for its ability to dissolve metals. At the time, the chemical nature of nitric acid was unknown, but its potential for various uses was clear.
During the medieval period, the methods for producing nitric acid evolved but remained linked to alchemical practices. Alchemists continued experimenting with saltpeter and sulfuric acid, refining the techniques to produce more nitric acid. This process was often carried out using rudimentary distillation techniques, where the combination of these two substances created nitric acid vapors, which were then condensed into a liquid form.
Though alchemists did not fully understand the chemical principles behind the reactions, they unknowingly laid the groundwork for modern chemistry. Their work with nitric acid contributed to the eventual rise of scientific methods in chemistry, allowing later scholars to understand the precise chemical composition and properties of the substance.

In its early days, nitric acid was primarily used by alchemists, who valued it for its ability to dissolve metals. This mystical approach focused on transforming base materials, such as metals, into more valuable substances. However, as the scientific method gained ground in the 16th and 17th centuries, the study of nitric acid shifted from alchemy to chemistry. Nitric acid became a key substance in modern chemistry, where its chemical properties were studied, leading to a deeper understanding of reactions and compounds.
As science progressed, nitric acid was recognized not only for its practical uses but also for its role in chemical reactions and industrial applications. Its properties as a strong oxidizing agent made it essential for numerous scientific advancements.
In the 17th century, Johann Rudolf Glauber, a German chemist, made a significant contribution to nitric acid production. He improved the process by adding sulfuric acid to potassium nitrate, a method that created nitric acid more efficiently. Glauber's method was important because it increased the purity of the acid and made the production process more reliable, laying the groundwork for further advancements in the industrial use of nitric acid. His innovation made nitric acid more accessible to the growing fields of chemistry and industry.
The 18th century marked a turning point for nitric acid in the world of chemistry. In the 1780s, Henry Cavendish, an English scientist, conducted groundbreaking experiments that confirmed the chemical composition of nitric acid. He showed that nitric acid is a compound formed by the combination of nitrogen, oxygen, and hydrogen. This discovery was crucial for understanding the properties of nitric acid and its role in chemical reactions.
