1 We show that the rate of OH conversion into Cl2 - is determined by the equilibrium concentration of the ionic pair H3O+ Cl-. hydronium ion endogenous retrovirus group W member 5 Homo sapiens
2 According to the proposed mechanism, the diffusional encounter of OH and H3O+ Cl- is followed by fast concerted charge/proton transfer ( k(25 C) = 6.2 x 1012 s-1) to yield Cl , which then reacts with Cl- to produce Cl2 -. hydronium ion endogenous retrovirus group W member 5 Homo sapiens
3 The mechanism has been confirmed by the observed first-order growth of the Cl2 - absorption and a direct proportionality of the rate constant to the activities of H3O+ and Cl- ions. hydronium ion endogenous retrovirus group W member 5 Homo sapiens
4 The salt effect on the rate of Cl2 - formation is due to the ionic strength effect on the equilibrium H3O+ + Cl- H3O+ Cl-. hydronium ion endogenous retrovirus group W member 5 Homo sapiens
5 The salt effect on the rate of Cl2 - formation is due to the ionic strength effect on the equilibrium H3O+ + Cl- H3O+ Cl-. hydronium ion endogenous retrovirus group W member 5 Homo sapiens
