Acetic acid / əˈsiːtɪk /, systematically named ethanoic acid / ˌɛθəˈnoʊɪk /, is an acidic, colourless liquid and organic compound with the chemical formula CH3COOH (also written as CH3CO2H, C2H4O2, or HC2H3O2 ). Vinegar is at least 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water.
Formula: C 2 H 4 O 2. Molecular weight: 60.0520. IUPAC Standard InChI:InChI=1S/C2H4O2/c1-2 (3)4/h1H3, (H,3,4) Copy. IUPAC Standard InChIKey:QTBSBXVTEAMEQO-UHFFFAOYSA-N Copy. CAS Registry Number: 64-19-7.
Apr 15, 2024 · Calculate the pH of a solution of a weak monoprotic weak acid or base, employing the "five-percent rule" to determine if the approximation 2-4 is justified. Predict whether an aqueous solution of a salt will be acidic or alkaline, and explain why by writing an appropriate equation.
The acid dissociation constant (pK a) of ethanoic acid in a solution of water is 4.76. The conjugate base of acetic acid is acetate, given by CH 3 COO – . The pH of an ethanoic acid solution of 1.0M concentration is 2.4, which implies that it does not dissociate completely.

An example of a weak acid is acetic acid, CH 3 COOH , which is present in vinegar. Acetic acid dissociates partially in water to form hydronium and acetate ions, CH 3 COO − : CH 3 COOH ( a q ) + H 2 O ( l ) ⇌ H 3 O + ( a q ) + CH 3 COO − ( a q )
