In the title hydrated salt, C9H8NO+·C8H4NO6-·H2O, the deprotonated carboxylate group is almost normal to its attached benzene ring [dihedral angle = 83.56 (8)°], whereas the protonated carboxylate group is close to parallel [dihedral angle = 24.56 (9)°]. In the crystal, the components are linked by N - H⋯O and O - H⋯O hydrogen bonds, generating  chains. The packing is consolidated by C - H⋯O and π-π [centroid-to-centroid distances = 3.6408 (9) and 3.6507 (9) Å] interactions, which result in a three-dimensional network.
