Question
When sulphuric acid reacts with the sodium chloride, the product obtained is the hydrochloric acid because:
- The boiling point of sulphuric acid is lower than hydrochloric acid.
- Sulphuric acid is having higher boiling point than hydrochloric acid
- The boiling point of hydrochloric acid is more than sulphuric acid.
- Both acids have the same boiling point.
Hint:
Sulphuric acid has high boiling point.
The correct answer is: Sulphuric acid is having higher boiling point than hydrochloric acid
The reaction of sodium chloride and sulphuric acid produces hydrochloric gas as a by-product. The gas hydrogen chloride escapes from the medium so the reaction cannot take place in a backward direction, and thus the reaction is irreversible.
The product obtained is the hydrochloric acid because sulphuric acid is having higher boiling point than hydrochloric acid.
