Ph–COOH + NaOH $\underset{}{\overset{}{\to }}$ Ph–COONa + H₂O   ;            Ph–CH₂OH + NaOH $\underset{}{\overset{}{\to }}$ No reaction

 $\therefore$ Can be separated

Ph–COOH + NaHCO₃ $\underset{}{\overset{}{\to }}$ Ph–COONa + H₂O + CO₂ ; Ph–CH₂OH + NaHCO₃ $\to$ No reaction

$\therefore$ Can be separated

Ph–CH₂OH + NaOH $\underset{}{\overset{}{\to }}$ No reaction  ; Ph–CH₂–COOH + NaOH $\to$ Ph–CH₂–COONa + H₂O

$\therefore$ Can be separated

Ph–CH₂OH + NaHCO₃ $\to$ No reaction ;

Ph – CH₂COOH + NaHCO₃ $\to$ Ph–CH₂COONa + H₂O + CO₂

$\therefore$ Can be separated
