Question

Phenol and benzoic acid is separated by

• A. $NaHC{O}_3$
• B. NaOH
• C. Na
• D. $NaN{H}_2$

Answer 1

Answer: (A)

Phenol and benzoic acid is separated by $NaHC{O}_3$

$PhOH+NaHC{O}_3\to$ No reaction

$\text{PhCOOH}\text{+}{\text{NaHCO}}_{\text{3}}\to {\text{PhCOO}}^{-}{\text{Na}}^{+}\text{+}{\text{H}}_{\text{2}}\text{O}\text{+}{\text{CO}}_{\text{2}}$
