Answer» Solution :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 .
