Metals often form several cations with different charges. Cerium, for example, forms Ce³+ and Ce4+ ions, and thallium forms Tl† and TI³+ ions. Cerium and thallium ions react as follows: 2Ce++ (aq) + TI* (aq)→2Ce³+(aq) +TI³+ (aq) This reaction is very slow and is thought to occur in a single elementary step. The reaction is catalyzed by the addition of Mn²2+(aq) according to the following mechanism: Ce4+ (aq) + Mn²+(aq) → Ce³+(aq) + Mn³+(aq) Ce4+ (aq) + Mn³+(aq) → Ce³+(aq)+ Mn4+(aq) Mn4+(aq) + Tl+(aq) + Mn2+ (aq)+T³+ (aq)
