The hydrolysis of 4 NH Cl produces a strong acid (HCl) and a weak base ( 4 NH OH ). The reaction is given below. 4 2 4 NH Cl H O NH OH HCl The ammonium ion reacts with water to form IONIC EQUILIBRIUM 65 ammonium hydroxide. 4 2 4 Initial Concentration: c 0 0 Final Concentration: c 1 – x cx cx NH H O NH OH H Therefore, the concentration of + H = cx Since the ammonium ion is hydrolyzed we can replace ‘x’ with ‘h’ which is the degree of hydrolysis. So, H = ch Now, Hydrolysis constant, 2
