KNO3 : salt of strong acid-strong base, solution is neutral, pH = 7. CH4COONa: salt of weak acid-strong base, solution is basic, pH > 7.
NH4Cl: salt of strong acid-weak base, solution is acidic, pH < 7.
C6H5COONH4 : both weak put NH4OH is slightly stronger than C6H5COOH, pH close to 7 but slightly > 7.
Hence, in order of pH, NH4Cl < C6H5COONH4 < KNO3 < CH3COONa
