Addition of methanol decreases AG", AH' and As0 of the exchange of Naf or Cs+ for H+ in tin(W) antimonate. Thus, the increase of selectivity constant is due to the decrease in the enthalpy term. On going from 30 to 90% (w/w) methanol, negative enthalpy and entropy changes occur may be due to chemiso
## Abstract The first row transition metal ions Mn^2+^, Co^2+^, and Ni^2+^ have been studied by classical umbrella sampling molecular dynamics simulations. The water exchange mechanisms, estimates of reaction rates, as well as structural changes during the activation process are discussed. Mn^2+^ w
