WebAn Introduction to Phenol Acidity. Phenol is an organic compound that has a benzene ring with a hydroxyl group (-OH) attached. It is a weak acid, with a Ka of 1.3 x 10-10. Phenol is soluble in water and is a colorless, crystalline solid. When phenol is dissolved in water, the phenol molecule donates a proton (H+) to the water molecule. Phenol is an organic compound appreciably soluble in water, with about 84.2 g dissolving in 1000 mL (0.895 M). Homogeneous mixtures of phenol and water at phenol to water mass ratios of ~2.6 and higher are possible. The sodium salt of phenol, sodium phenoxide, is far more water-soluble. Phenol is a weak acid. In aqueous solution in the pH range ca. 8 - 12 it is in equ… Webphenol and phenoxide ion both are stabilized by resonance. In case of phenol the lone pair on oxygen atom get delocalize over the ring and if we look into the resonance structures of phenol there is a charge seperation i.e. there is positive charge on oxygen atom and negative charge on the ring carbons.
