"Glacial acetic acid" is a name for water-free acetic acid. Similar to the German name "Eisessig" ("ice vinegar"), the name comes from the solid ice-like crystals that form with agitation, slightly below room temperature at 16.6 °C (61.9 °F). Acetic acid can never be truly water-free in an atmosphere that contains water, so the presence of 0. ...

Organic solutions can be dried using a range of drying agents. Typically following a workup the organic extract is dried using magnesium sulfate or a similar drying agent to remove most remaining water. [5] Anhydrous acetic acid is known as glacial acetic acid.
In addition to this acetic acid vapour pretreatment, there is also a pretreatment in a thin-pulp state. In this process, the cellulose is introduced into large quantities of water or diluted acetic acid and intensively stirred. Subsequent process steps such as pressing or centrifuging constantly increase the concentration of cellulose in the pulp.

Notable descaling agents include acetic acid, citric acid, glycolic acid, formic acid, lactic acid, phosphoric acid, sulfamic acid and hydrochloric acid. The calcium salts are soluble and thus washed away during dissolution or solvation. The speed of the descaling action depends on the concentration and acidity or pH of the solution provided ...

It is the conjugate base of acetic acid. Above a pH of 5.5, acetic acid converts to acetate: [1] CH 3 COOH ⇌ CH 3 COO − + H + Many acetate salts are ionic, indicated by their tendency to dissolve well in water. A commonly encountered acetate in the home is sodium acetate, a white solid that can be prepared by combining vinegar and sodium ...
