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


#RC(=O)OH + OH^(-) rarr RC(=O)O^(-) + H_2O#
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.
