Muriatic acid is another name for which of the following substances?

Muriatic acid is a common name for hydrochloric acid, a strong and highly corrosive acid with the chemical formula HCl. This substance is widely used in various applications, including the cleaning of masonry, pH control in swimming pools, and the manufacture of chlorides and fertilizers.

Hydrochloric acid is known for its ability to dissolve minerals and is typically found in a diluted form for safety in many consumer and industry-related applications. Understanding that muriatic acid is essentially hydrochloric acid is important not only for identification but also for recognizing its uses and handling precautions, especially in wastewater treatment where its properties might be significant in pH adjustment and neutralization processes.

The other substances listed, such as ferric chloride, sodium hydroxide, and sulfuric acid, are distinct compounds with different chemical properties and applications, making them unrelated to the identity of muriatic acid.
