Acetic acid or ethanoic acid is a colourless liquid organic compound. When acetic acid is dissolved in water, it is termed glacial acetic acid. It is a weak acid since the solution dissociates only slightly.
dissolved: slightly soluble in water, soluble in hot organic solvents such as ethanol, acetone, acetic acid Diphenic Acid can form a variety of container polymers. It also shows the phenomenon of reverse structure, which is a three -dimensional heterogeneous phenomenon that is caused by the restr...
