Phenol + naoh
WebHowever, phenol is sufficiently acidic for it to have recognisably 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. Phenol is a very weak acid and the position of equilibrium lies well to the left. Phenol can lose a hydrogen ion because the phenoxide ion formed is ... WebGroup I metal hydroxides (LiOH, NaOH, etc.) Group II metal hydroxides (Mg(OH)2, Ba(OH)2, etc.) Strong bases completely dissociate in aq solution (Kb > 1, pKb < 1). Conjugate acids (cations) of strong bases are ineffective bases. * Compiled from Appendix 5 Chem 1A, B, C Lab Manual and Zumdahl 6th Ed. The pKa values for organic acids can be found in

Webreaction of phenol and NaOH lies almost completely to the right: Because the difference in pK a values of water and phenol is about 6, the equilibrium constant for this reaction is about 106 (Sec. 3.4E). Thus, for all practical purposes, phenols are con-verted completely into their conjugate-base anions by NaOH solution. Although the stronger
