Glacial acetic acid is used in analytical chemistry for the estimation of weakly alkaline substances such as organic amides. Glacial acetic acid is a much weaker base than water, so the amide behaves as a strong base in this medium. It then can be titrated using a solution in glacial acetic acid of a very strong acid, such as perchloric acid. [52]

Uses formula: = + for T = 0 to 36 °C = + for T = 36 to 170 °C Formula from Lange's Handbook of Chemistry , 10th ed. log 10 of acetic acid vapor pressure vs. temperature.
TAE buffer is commonly prepared as a 50× stock solution for laboratory use. A 50× stock solution can be prepared by dissolving 242 g Tris base in water, adding 57.1 ml glacial acetic acid, and 100 ml of 500 mM EDTA (pH 8.0) solution, and bringing the final volume up to 1 litre.
The strength of an inorganic acid is dependent on the oxidation state for the atom to which the proton may be attached. Acid strength is solvent-dependent. For example, hydrogen chloride is a strong acid in aqueous solution, but is a weak acid when dissolved in glacial acetic acid.
Heating Zn(CH 3 CO 2) 2 in a vacuum results in a loss of acetic anhydride, leaving a residue of "basic zinc acetate," with the formula Zn 4 O(CH 3 CO 2) 6.It can also be prepared by a reaction of glacial acetic acid with zinc oxide. [12]
Carnoy's solution is a fixative composed of 60% ethanol, 30% chloroform and 10% glacial acetic acid, 1 gram of ferric chloride. [1] [2]Carnoy's solution is also the name of a different fixation composed of ethanol and glacial acetic acid (3:1).
