Acetic acid (wanda kuma ake kira acetic acid, glacial acetic acid, ko ma'anar CH COOH) wani acid mono acid ne wanda ₃ shine tushen acidity da wari a cikin vinegar. Pure anhydrous acetic acid (glacial acetic acid) ruwa ne na hygroscopic mara launi tare da daskarewa na 16.7 ° C (62 ° F) kuma ya zama crystal mara launi akan ƙarfafawa. Ko da yake acetic acid acid ne mai rauni dangane da ikonsa na rabuwa a cikin maganin ruwa, acetic acid yana lalata kuma tururinsa suna damun idanu da hanci.
acetic acid, cikakken carboxylic acid mai dauke da atom na carbon guda biyu, wani muhimmin abin da ke dauke da iskar oxyid na hydrocarbons. Tsarin kwayoyin halitta C2H4O₂, tsarin tsarin kwayoyin halitta

Gajeren CH₃COOH, HAC shine gajeriyar tsari. Ƙungiya mai aiki na tsarin tsari shine ƙungiyar carboxyl kuma lambar CAS ita ce 64-19-7. Domin shine babban bangaren vinegar, wanda kuma aka sani da acetic acid. A cikin 'ya'yan itatuwa ko kayan lambu mai, alal misali, yawanci a cikin nau'i na esters na mahadi; Yana samuwa azaman acid kyauta a cikin kyallen takarda, najasa, da jinin dabbobi. Na al'ada vinegar ya ƙunshi 3% zuwa 5% acetic acid. Acetic acid ruwa ne mara launi tare da ƙaƙƙarfan ƙamshi. A zumunta kwayoyin nauyi ne 60.05, da narkewa batu ne 16.6 ℃, da tafasar batu ne 117.9 ℃, da dangi yawa ne 1.0492 (20/4 ℃), da yawa ne mafi girma fiye da na ruwa, da refractive index ne 1.3716. Pure acetic acid zai iya samar da ƙanƙara mai kama da ƙanƙara a ƙasa da 16.6 ° C, don haka galibi ana kiran shi glacial acetic acid. Mai narkewa a cikin ruwa, ethanol, ether da carbon tetrachloride. Lokacin da aka ƙara ruwa zuwa acetic acid, jimlar ƙarar ta zama ƙarami kuma yawan adadin yana ƙaruwa har sai adadin kwayoyin halitta ya kasance 1: 1, daidai da samuwar mono-acid CH3C (OH) ₃, wanda aka ƙara diluted kuma baya canzawa a girma. .
