H3PO4 vs. HClO
What's the Difference?
H3PO4, also known as phosphoric acid, and HClO, also known as hypochlorous acid, are both acids with different chemical compositions and properties. H3PO4 contains phosphorus, hydrogen, and oxygen atoms, while HClO contains chlorine, hydrogen, and oxygen atoms. Phosphoric acid is commonly used in the food and beverage industry as a flavoring agent and preservative, while hypochlorous acid is a powerful disinfectant and sanitizer. Both acids are important in various industrial and scientific applications, but they serve different purposes due to their distinct chemical structures and reactivity.

Further Detail
Introduction
Phosphoric acid (H3PO4) and hypochlorous acid (HClO) are two important acids with distinct chemical properties. In this article, we will compare the attributes of these two acids, including their chemical structures, physical properties, uses, and reactivity.
Chemical Structure
H3PO4, also known as orthophosphoric acid, is a triprotic acid with the chemical formula H3PO4. It consists of three hydrogen atoms, one phosphorus atom, and four oxygen atoms. On the other hand, HClO, or hypochlorous acid, is a weak acid with the chemical formula HClO. It contains one hydrogen atom, one chlorine atom, and one oxygen atom.
Physical Properties
H3PO4 is a colorless, odorless liquid with a syrupy consistency. It has a high melting point of 42.35 degrees Celsius and a boiling point of 158 degrees Celsius. In contrast, HClO is a pale yellow solution with a pungent odor. It is highly reactive and unstable, decomposing easily into chlorine and oxygen.
Uses
H3PO4 is commonly used in the food industry as a flavor enhancer and acidulant. It is also used in the production of fertilizers, detergents, and metal phosphates. On the other hand, HClO is used as a disinfectant and bleaching agent. It is effective in killing bacteria and viruses, making it a valuable tool in water treatment and sanitation.
Reactivity
H3PO4 is a weak acid that dissociates into three hydrogen ions and one phosphate ion in aqueous solutions. It can react with bases to form salts and water. HClO, on the other hand, is a strong oxidizing agent that can react with organic compounds to form chlorinated products. It is also capable of oxidizing metals and reducing agents.
Conclusion
In conclusion, H3PO4 and HClO are two important acids with unique properties and uses. While H3PO4 is a triprotic acid commonly used in the food and chemical industries, HClO is a powerful disinfectant and bleaching agent. Understanding the differences between these two acids is essential for their proper use in various applications.
