WebHowever, phenol is sufficiently acidic for it to have recognizably acidic properties - even if it is still a very weak acid. A hydrogen ion can break away from the -OH group and transfer to a base. The pKa of ethanol is about 17, while the pKa of acetic acid is about 5: this is a 10 12 -fold difference in the two acidity constants. WebA liquid containing over 50% phenol. See Phenol (solid). Phenols do not behave as organic alcohols, as one might guess from the presence of a hydroxyl (-OH) group in their structure. Instead, they react as weak organic acids. Phenols and cresols are much weaker as acids than common carboxylic acids (phenol has pKa = 9.88).
