Acetic acid can never be truly water-free in an atmosphere that contains water, so the presence of 0.1% water in glacial acetic acid lowers its melting point by 0.2 °C. [ 9 ] A common symbol for acetic acid is AcOH (or HOAc), where Ac is the pseudoelement symbol representing the acetyl group CH 3 −C(=O)− ; the conjugate base , acetate ( CH ...
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 ...
In the presence of a strong acid catalyst, such as sulfuric acid, acetic acid and hydrogen peroxide produce peracetic acid: [3] H 2 O 2 + CH 3 CO 2 H ⇌ CH 3 CO 3 H + H 2 O. However, in concentrations (3-6%) of vinegar and hydrogen peroxide marketed for household use, mixing without a strong acid catalyst will not form peracetic acid.
Most automotive engines are "water"-cooled to remove waste heat, though the "water" used is actually a mixture of water and antifreeze. The term engine coolant is widely used in the automotive industry, which covers its primary function of convective heat transfer for internal combustion engines .
More dramatically, a long-chain hydrocarbon like squalene (C 30 H 62) has a viscosity an order of magnitude larger than the shorter n-alkanes (roughly 31 mPa·s at 25 °C). This is also the reason oils tend to be highly viscous, since they are usually composed of long-chain hydrocarbons.
The density of water indeed. You might also want to see density of water and ice. --Borbrav 23:25, 1 December 2005 (UTC) The density of water is the reference value for specific gravity; water is defined to have a specific gravity of 1. ‣ᓛᖁ ᑐ 00:01, 2 December 2005 (UTC)

Additionally, dogs have much larger olfactory mucosa and a larger part of the brain dedicated to odors. Whereas in humans, 5% of the brain is dedicated to odors, in dogs this figure is 33%. Dogs are able to detect odors 9 orders of magnitude more faint than humans, who can detect odors up to 1 ppb. [9]: 30
