Abstract
Hydrogen chloride (HCl) dissociates completely in water to hydronium (H3O) and chloride (Cl -) ions. However, the extent of HCl ionization on cold ice remains unclear. We studied HCl ionization on the surface of ice by a Cs + reactive ion scattering (RIS) method. Molecular and ionized states of HCl were unambiguously identified, and their relative portions were quantified at various ice temperatures. There is increasing interest for studying reactions on ice. Such interest arises from the quest for knowledge about the catalytic role of polar stratospheric clouds (PSCs) in ozone depletion, 1-3
