He can test with blue and red litmus solutions. NaCl solution is neutral. It will neither turn blue litmus red nor red litmus blue. `NH_(4)Cl` solution is acidic. It will turn blue litmus red but will have no effect on red litmus `Na_(2)CO_(3)` solution is basic. It will turn red litmus blue but will have no effect on blue litmus .
