... HCl. HCl is one of the few strong acids and H2S is not. Also, Cl– is more electronegative than S2– so the bond is more polar in HCl, and Cl– will be the more stable conjugate base. b) H2SO3 (aq) or HClO3 (aq) HClO3. Cl is more electronegative than S. Because there are the same number of O's, the mor ...
