Question:
Arrange the following in increasing order of pH
KNO3 (aq), CH3COONa (aq), NH4Cl (aq), C6 H5COONH4 (aq)
Solution:
The increasing order of pH will be;
CH3COONa< KNO3< C6H5COONH4 CH3COONa is a salt of a weak acid (CH3COOH) and strong base (NaOH) KNO3 is a salt of strong acid (HNO3)-strong base (KOH) C6H5COONH4 is a salt of a weak acid (benzoic acid) and weak base (NH4OH) NH4Cl is a salt of a strong acid (HCl) and a weak base (NH4OH)
