Muriatic acid is indeed chemically known as hydrochloric acid. This strong, corrosive acid is commonly used for various applications, including cleaning, etching metal, and adjusting the pH levels in swimming pools. The primary active ingredient in muriatic acid is hydrogen chloride, which, when dissolved in water, forms hydrochloric acid.

Hydrochloric acid is recognized for its ability to dissociate fully in water, releasing hydrogen ions that contribute to its acidity. This characteristic makes it an effective agent in both industrial and household cleaning processes, reinforcing its widespread use as "muriatic acid."

Other acids mentioned, such as sulfuric acid, acetic acid, and phosphoric acid, possess different chemical structures and properties. Sulfuric acid, for example, contains sulfate ions and is known for its use in batteries and fertilizers. Acetic acid is a weaker acid primarily used in food preservation and flavoring, whereas phosphoric acid has applications in fertilizers and food processing. Therefore, understanding the specific chemical composition of muriatic acid as hydrochloric acid is essential for correctly identifying its uses and characteristics.
