It will be more soluble in a basic solution. Of course, it will be present in solution as its conjugate base, the carboxylate ion.

#### Explanation:

$R C \left(= O\right) O H + O {H}^{-} \rightarrow R C \left(= O\right) {O}^{-} + {H}_{2} O$
A base will react with a weak acid to give the appropriate products. The charged species should be more soluble in aqueous solution than its parent acid.
