Water Exchange
The exchange between bulk and coordinated water is of fundamental interest as a measure of the intrinsic kinetic lability of metal ions. This rate is relevant to toxicity, catalysis, magnetic resonance imaging, and other effects. For octahedral mono- and dicationic aquo complexes, these exchange processes occur via an interchange pathway that has more or less dissociative character. Rates vary by a factor of 1018, 3+ being the slowest and + being one of the fastest for octahedral complexes. Charge has a significant influence on these rates but non-electrostatic effects are also important.

“So when Pilate saw that he could do nothing, but rather that a riot was beginning, he took some water and washed his hands before the crowd, saying, “I am innocent of this man’s blood; see to it yourselves.””
—Bible: New Testament, Matthew 27:24.
“Ants are so much like human beings as to be an embarrassment. They farm fungi, raise aphids as livestock, launch armies into war, use chemical sprays to alarm and confuse enemies, capture slaves, engage in child labor, exchange information ceaselessly. They do everything but watch television.”
