Chromic acid anion
WebChromic acid and chromates are widely used in many applications. Anion exchange offers an ideal opportunity for the removal and recovery of chromates. Both strongly and weakly base resins can be applied. In aqueous solutions chromate ions exist in different ionic forms. The speciation mainly depends on the pH value. WebPhenols are usually oxidized to a brown tar by chromic acid. 3. Acidity of Phenols. Most phenols are weaker acids than carboxylic acids and stronger acids than alcohols. When phenols react with a base the phenol is converted into a phenoxide anion (see reactions below). The phenoxide anion is more soluble in water than the corresponding phenol.
