An industrial chemist treats solid NaCl with concentrated H₂SO₄ and obtains gaseous HCl and NaHSO₄. When she substi-tutes solid NaI for NaCl, gaseous H₂S, solid I₂, and S₈ are ob-tained but no HI. (a) What type of reaction did the H₂SO₄ undergo with NaI? (b) Why does NaI, but not NaCl, cause thistype of reaction? (c) To produce HI(g) by the reaction of NaI with an acid, how does the acid have to differ from sulfuric acid?
