What is H2S04?

H2S04, commonly known as sulfuric acid, is a colorless, odorless, and oily liquid that is highly corrosive and reactive. It is classified as a strong acid due to its ability to completely dissociate in aqueous solutions, releasing hydrogen ions (H+) and sulfate ions (SO42-). This property makes H2S04 extremely useful in various chemical reactions and industrial applications.

Historical Background

The history of sulfuric acid dates back to the 8th century when it was first discovered by the Persian alchemist Jabir ibn Hayyan. It was later produced in larger quantities during the 17th century, leading to its widespread use in chemical processes. Today, sulfuric acid is one of the most produced industrial chemicals globally, with millions of tons manufactured each year.
