Hydrochloric Acid vs. Muriatic Acid: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Published on November 26, 2023
Hydrochloric acid is a pure, laboratory-grade acid (HCl); muriatic acid is a less pure, industrial-grade variant of hydrochloric acid.

Key Differences

Hydrochloric acid is a strong, corrosive acid composed of hydrogen and chlorine (HCl). It is commonly used in scientific research and industrial applications for its reactive properties. Muriatic acid, on the other hand, is essentially the same chemical compound but often less pure and more diluted. It is used for more general purposes, like in household cleaning and pool maintenance.

In terms of purity, hydrochloric acid is typically more refined and has fewer impurities, making it suitable for precise laboratory work and chemical synthesis. While, muriatic acid often contains impurities and additives, which make it less suitable for lab applications but more practical and cost-effective for commercial and residential use.

Hydrochloric acid is generally available in higher concentrations and is used in applications requiring a high degree of chemical reactivity, such as in the production of chlorides, dyes, and fertilizers. Muriatic acid, being less concentrated, is safer for non-professional use, commonly used for cleaning masonry or adjusting the pH of swimming pools.

Safety measures for handling hydrochloric acid are stringent due to its high reactivity and concentration, requiring specialized equipment and training. Muriatic acid, while still dangerous, is typically handled with standard safety precautions like gloves and eye protection, owing to its lower concentration.
