In the reaction of sodium chloride with sulfuric acid, no redox reactions are occurring.Concentrated sulphuric acid isn't a strong enough oxidising agent to oxidise fluoride or chloride ions.The sulfuric acid acts as an acid and donates a proton to the halide.Misty fumes of HCl are observed.NaCl + H2SO4 → NaHSO4 + HCl
Sodium Chloride
