← ScienceWhich outcome occurs when concentrated sulfuric acid reacts with sodium chloride?
A)Hydrogen chloride gas is produced✓
B)Chlorine gas spontaneously combusts
C)Sodium sulfate immediately precipitates
D)An exothermic redox reaction begins
💡 Explanation
Hydrogen chloride gas forms upon mixing because protonation via Bronsted-Lowry acid-base behavior releases HCl gas. HCl, being only weakly ionic, volatilizes therefore generating gas rather than remaining due to strong ionic bonds like other salts.
