What is the Difference Between Muriatic Acid and Hydrochloric Acid?

Muriatic acid and hydrochloric acid are almost the same, with a few differences in purity and concentration. Both are aqueous solutions of hydrogen chloride (HCl) and are classified as strong acids. The main points to consider are:

• Purity: Muriatic acid is a hydrochloric acid that contains impurities, making it somewhat stronger and usually giving it a yellowish color. Hydrochloric acid can be more pure and concentrated, with concentrations up to 38%.
• Concentration: Muriatic acid is generally of lower concentration compared to concentrated hydrochloric acid. Bulk industrial-grade muriatic acid is typically 30% to 35%.
• Terminology: Muriatic acid is an older known term, and it is just another name for hydrochloric acid. Both names are used interchangeably, and the choice between them may depend on regional preferences or specific applications.
• Uses: Both muriatic and hydrochloric acids are used for cleaning, as they can remove stains and unclog drains. They are also used in various industrial processes and laboratory settings.

In summary, muriatic acid and hydrochloric acid are essentially the same, with the main differences being purity and concentration. Both can be used interchangeably for cleaning and other applications, depending on the specific requirements and available products.

Comparative Table: Muriatic Acid vs Hydrochloric Acid

Muriatic acid and hydrochloric acid are essentially the same chemical compound, composed of hydrogen and chlorine (HCl). They are both strong acids with similar chemical properties. However, there are some differences between the two:

Despite these differences, the two acids are often used interchangeably in various applications, including cleaning and treating pool water. It is essential to handle both acids with care, as they can be corrosive and potentially dangerous if not used properly.
