Hello, We know that Sodium Chorite when acidified produces chlorine dioxide, but does Sodium Choride also produce a gas when acidified? Thanks!
Sodium Chorite is a salt of a weak Chlorous acid. The pure substance is unstable: 4*HClO2 = HCl + HClO3 + 2*ClO2 + H2O Sodium Chorite and Sulphuric acid reaction: 4*NaClO2 + 2*H2SO4 = 2*Na2SO4 + HCl + HClO3 + 2*ClO2 + H2O
Sodium Choride also produce a gas when acidified, but only by more strong acid, than Hydrochloric acid: NaCl + H2SO4 → NaHSO4 + HCl(gas)
