Vinegar is typically no less than 4% acetic acid by mass. [64] [65] [66] Legal limits on acetic acid content vary by jurisdiction. Vinegar is used directly as a condiment, and in the pickling of vegetables and other foods. Table vinegar tends to be more diluted (4% to 8% acetic acid), while commercial food pickling employs solutions that are ...
The term "distilled vinegar" as used in the United States (called "spirit vinegar" in the UK, "white vinegar" in Canada [39]) is something of a misnomer because it is not produced by distillation, but by fermentation of distilled alcohol. The fermentate is diluted to produce a colorless solution of 5 to 8% acetic acid in water, with a pH of ...
It is sometimes produced in a laboratory experiment by the reaction of acetic acid, commonly in the 5–18% solution known as vinegar, with sodium carbonate ("washing soda"), sodium bicarbonate ("baking soda"), or sodium hydroxide ("lye", or "caustic soda"). Any of these reactions produce sodium acetate and water.
Ethanol (grain alcohol) is a widely used and abused psychoactive drug. If ingested, the so-called "toxic alcohols" (other than ethanol) such as methanol , 1-propanol , and ethylene glycol metabolize into toxic aldehydes and acids, which cause potentially fatal metabolic acidosis . [ 30 ]
At relatively low alc/vol, the alcohol percentage by weight is about 4/5 of the alc/vol (e.g., 3.2% ABW is about 4% alc/vol). [25] However, because of the miscibility of alcohol and water, the conversion factor is not constant but rather depends upon the concentration of alcohol. [citation needed]
Bulk industrial-grade is therefore 30% to 35%, optimized to balance transport efficiency and product loss through evaporation. In the United States, solutions of between 20% and 32% are sold as muriatic acid. Solutions for household purposes in the US, mostly cleaning, are typically 10% to 12%, with strong recommendations to dilute before use.

Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula CH 3 CH 2 OH. It is an alcohol, with its formula also written as C 2 H 5 OH, C 2 H 6 O or EtOH, where Et stands for ethyl. Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like ...
