9.34. KCl is a salt of strong acid HCl and strong base KOH. Such salts are neutral in nature and do not undergo hydrolysis. In neutral water, acidic water, and alkaline water, KCl dissociates as
WaterKCl → ?K++Cl−
AlCl3? is a salt of strong acid HCl and weak base Al(OH)3?.(i) In normal water, it is hydrolyzed.
AlCl3?+3H2?O→Al(OH)3?+3H++3Cl−
(ii) In acidic water, H+ ions react with Al(OH)3? (obtained from the hydrolysis of AlCl3?) forming water and Al3+ ions. Hence it exists as Al3++Cl−
AlCl3? + acidifiedwater? → Al++3Cl&m...more
