The present invention provides binary azeotrope-like compositions comprising pentafluoroethane (HFC-125) and hydrogen chloride (HCl). In addition, the invention relates to methods for removing HFC-125 or HCl from a mixture of HFC-125 and HCl by distilling the mixture to remove an azeotrope-like composition of HFC-125 and HCl in the column distillate.
