Metals often form several cations with different charges. Cerium, for example, forms Ce3+ and Ce4+ ions, and thallium forms Tlt and TI+ jons. Cerium and thallium ions react as follows: 2Ce4+ (aq) + TI+ (aq)→2CE³+(aq) + T1³+ (aq) This reaction is very slow and is thought to occur in a single elementary step. The reaction is catalyzed by the addition of Mn²+(aq) according to the following mechanism: Ce+ (aq) + Mn²+(aq) → Ce³+(aq) + Mn³+ (aq) Ce+ (aq) + Mn³+(aq) → Ce³+(aq) + Mn4+ (aq) Mn1+ (aq) + TI+ (aq) → Mn2+ (aq) + Tl³+ (aq)
