I-hydrochloric acid (i-muriatic acid): igesi ye-hydrogen chloride encibilikiswe emanzini. I-asidi enamandla ekhipha intuthu, ethengiswa kusukela kuzixazululo ezihlanjululwe kuya cishe ku-37–40 % (i-specific gravity engaba ngu-1.2). Isetshenziselwa ukuhlanza izinsimbi nge-asidi, ukuncibilikisa itshe lomcako namaminerali, ukwenza ama-chloride nokulungisa i-pH. Ishisa isikhumba, amehlo namaphaphu; njalo faka i-asidi emanzini.
