WebApr 8, 2024 · Hint: Phenol has chemical formula C 6 H 5 O H and its aqueous solution is weakly acidic in nature while NaOH (sodium hydroxide) is a strong base and hence, the reaction between phenol and sodium hydroxide is an acid-base reaction. It is also known as the neutralization reaction and hence salt and water will be formed. Complete answer: WebSep 11, 2024 · Phenols are weak acids – in water, they ionize slightly to form phenoxide ion and hydronium ion, which makes the solution acidic. If phenol is reacted with NaOH (a strong base), it is completely converted to the phenoxide ion, which is soluble in water because it is charged. Phenol itself is not very soluble in water.
