Metals often form several cations with different charges.Cerium, for example, forms Ce³+ and Ce4+ ions, andthallium forms Tl* and TI³+ ions. Cerium and thalliumions react as follows:2Ce4+ (aq) + TI+ (aq)→2CE³+ (aq)+ T1³+ (aq)This reaction is very slow and is thought to occur in asingle elementary step. The reaction is catalyzed by theaddition of Mn2+(aq) according to the followingmechanism:Ce+ (aq) + Mn²+ (aq) → Ce³+(aq) + Mn3+ (aq)Cet+ (aq) + Mn³+(aq) → Ce³+(aq) + Mn+ (aq)Mn4+ (aq) + TI+(aq)→ Mn²+(aq) + T1³+ (aq) The catalyzed reaction is first order in [Ce+] and first order in [Mn2+].
