Web(c) Titrant volume = 25.00 mL. This titrant addition involves a stoichiometric amount of base (the equivalence point), and so only products of the neutralization reaction are in solution (water and NaCl).Neither the cation nor the anion of this salt undergo acid-base ionization; the only process generating hydronium ions is the autoprotolysis of water. WebApr 7, 2024 · Phenols are the organic compounds having benzene ring bonding to a hydroxyl group, which are also known as carbolic acids (phenol carbolic acid). Phenols usually react with active metals such as potassium, sodium and forms phenoxide. Happening such reactions of phenols with metals indicates it is acidic in nature. overleaf share project
