	an introduction to acid anhydrides
		Ethanoic anhydride is a colourless liquid, smelling strongly of vinegar (ethanoic acid).
		The smell is because ethanoic anhydride reacts with water vapour in the air (and moisture in your nose) to produce ethanoic acid again.
		Ethanoic anhydride can't be said to dissolve in water because it reacts with it to give ethanoic acid.

	Carboxylic Acid Reactivity
		Acetic acid is ten times weaker an acid than formic acid (first two entries in the second row), confirming the electron donating character of an alkyl group relative to hydrogen, as noted earlier in a discussion of carbocation stability.
		Reactions in which the hydroxyl group of a carboxylic acid is replaced by another nucleophilic group are important for preparing functional derivatives of carboxylic acids.
		Acid catalysis is necessary to increase the electrophilic character of the carboxyl carbon atom, so it will bond more rapidly to the nucleophilic oxygen of the alcohol.

	Acetic acid - Wikinfo
		Acetic acid is a molecule central to biochemistry, and is produced in some amount by nearly all forms of life.
		In aqueous solution, acetic acid can lose the proton of its carboxyl group, turning into the acetate ion CH The pKa of acetic acid is about 4.8 at 25 °C, meaning that about half of the acetic acid molecules are in the acetate form at a pH of 4.8.
		Acetic acid, when complexed with coenzyme A, is central to the metabolism and biosynthetic processes of almost all forms of life.

	Acids and Alkalis (Site not responding. Last check: )
		almost all of the acid is in the form of hydrogen ions and the negative ions associated with the acid (sulphate, chloride or whatever).
		In this way, an equilibrium is set up in which the rate at which covalent ethanoic acid is breaking up to form ions is the same as the rate at which the ions are recombining to form the covalent molecules.
		For instance, sulphuric acid is a strong acid, but if you put a single drop of sulphuric acid in a bath of water, the solution would be so weakly acidic that it wouldn't even be detectable.

		Actually, the manufacture of vinegar is a two-stage process -- (a) the conversion of sugar to alcohol by yeast; and (b) the conversion of alcohol to acetic acid by bacteria.
		Commercially, the acid is usually produced by such chemical processes as the oxidation of acetaldehyde with air in the presence of catalysts.
		Acetic acid is an important organic acid and industrial chemical.

	Carboxylic Acids and Derivatives
		Carboxylic acids are particularly good at hydrogen bonding to other carboxylic acids and so tend to have rather high boiling points and melting points than other molecules of similar size and shape.
		Ethanoic acid has a slightly higher viscosity, and a slightly higher boiling point than does water.
		Considering that butanoic acid gives rise to the acrid smell of rancid milk, while ethyl butanoate gives rise to the tarty aroma of fresh pineapple, it is clear that converting a carboxylic acid to an ester can have a dramatic effect on the physical and chemical properties of the acid.

	Titrations, Indicators and Titration Curves
		When an acid and base have been mixed in equivalent amounts (according to the chemical equation for the reaction) they are said to have neutralised each other.
		For example, at the equivalence point of a titration involving ethanoic acid and sodium hydroxide, the only product is an aqueous solution of the ionic compound sodium ethanoate.
		It is the ethanoate ions behaving as a base that cause the solution at the end-point to have an alkaline pH.

	Greener Industry - Ethanoic Acid - Production Method
		Up to the 1970s, ethanoic acid was produced industrially by the direct oxidation of naptha or butane, and this process is still in operation in some countries.
		Ethanoic acid was also made by the oxidation of ethene via the Wacker process.
		Since 1997, ethanoic acid is increasingly being produced by the BP Cativa process, also involving the carbonylation of methanol.

		I'm just thinking that "anhydrate" suggests that adding water to it will chemically change it into 5 moles of something else (like ethanoic acid?) and some of the water will be used up in the process.
		I'm not sure if you'd still have the same amount of Ethanoic anhydrate (anhydrite?) before and after adding the water.
		If we put a system together which has all the reactants on the left side but nothing on the right, it will tend to shift rightwards, that is some of the Anhydrate will combine with water to form Ethanoic Acid.
