Acetic Acid - an overview | ScienceDirect Topics
Acetic acid is an important bulk chemical, used as raw material in the production of vinyl acetate, terephtalic acid, acetate esters and acetic anhydride. All these processes include a step for separating the acetic acid from water, both high-purity and high-recovery of …
Acetic acid - Wikipedia
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.

SOLVED: How percentage purity of acetic acid can be
To determine the percentage purity of acetic acid, we can use a technique called acid-base titration. In this method, a solution of known concentration (called the titrant) is used to react with a solution of the analyte (in this case, acetic acid) to determine its concentration.
Hydrochloric Acid. — 5 cc. of acetic acid diluted with 50 cc. of water should afford no turbidity on the addition of 5 cc. of nitric acid followed by silver nitrate solution.
