WebThe water is separated into two streams (acid and alkaline) of ionized water. The acid water (oxidized) makes up about 30% of the water and the alkaline water 70%. As the body is slowly brought into pH balance by drinking Ionized Water, it will naturally begin to function more efficiently and problems will begin to correct themselves. In organic chemistry, phenols, sometimes called phenolics, are a class of chemical compounds consisting of one or more hydroxyl groups (−OH) bonded directly to an aromatic hydrocarbon group. The simplest is phenol, C 6H 5OH. Phenolic compounds are classified as simple phenols or polyphenols … Meer weergeven Acidity Phenols are more acidic than typical alcohols. The acidity of the hydroxyl group in phenols is commonly intermediate between that of aliphatic alcohols and carboxylic acids Meer weergeven Many phenols of commercial interest are prepared by elaboration of phenol or cresols.
