Here's why:

* Salicylic acid (C₇H₆O₃) is a weak acid with a carboxyl group (-COOH) that can donate a proton (H+) to form the salicylate ion.

* Salicylate (C₇H₅O₃-) is the conjugate base of salicylic acid.

Solubility:

* Salicylic acid is more soluble in water because the carboxyl group can form hydrogen bonds with water molecules, increasing its solubility.

* Salicylate is less soluble in water than salicylic acid. While it still has the potential to form hydrogen bonds, the negative charge on the salicylate ion makes it less attracted to the polar water molecules.

In summary:

* Salicylic acid (acidic form) is more soluble than salicylate (ionic form) due to the ability of the carboxyl group to form stronger hydrogen bonds with water.
