Although, phenoxide ion has more number of resonating structures than carboxylate ion, carboxylic acid is a stronger acid than phenol. Why ?

Although, phenoxide ion has more number of resonating structure than carboxylate ion, carboxylic acid is a stronger and than phenol. This is because, the negative charge is delocalized over two electronegative O – atoms in carboxylate ion whereas in phenoxide ion, the negative charge is less effectively delocalized over one oxygen atom and less electronegative C – atoms as shown below.
