Answer:
When heated, the pure 100% acid loses sulfur trioxide gas, SO 3, until a constant-boiling solution, or azeotrope, containing about 98.5% H 2SO 4 is formed at 337°C. Concentrated sulfuric acid is a weak acid (see acids and bases ) and a poor electrolyte because relatively little of it is dissociated into ions at room temperature. When cold it does not react readily with such common metals as iron or copper. When hot it is an oxidizing agent, the sulfur in it being reduced; sulfur dioxide gas may be released. Hot concentrated sulfuric acid reacts with most metals and with several nonmetals, e.g., sulfur and carbon. Because the concentrated acid has a fairly high boiling point, it can be used to release more volatile acids from their salts, e.g., when sodium chloride (NaCl), or common salt, is heated with concentrated sulfuric acid, hydrogen chloride gas, HCl, is evolved.
