2 4. Write the formula of each anion: a) sulfide S 2- b) sulfite SO 3 2- c) sulfate SO 4 2- d) hydrogen sulfate HSO 4 2- 5. Write balanced formula unit, total ionic, and net ionic equations for the reactions (if any) that occur when solutions of the following compounds are mixed: a) BaCl 2 and Na 2 SO 4 BaCl 2 (aq) + Na 2 SO 4 (aq) 2NaCl(aq) + BaSO 2 (s) Ba 2+ (aq) + Cl - (aq) + 2Na + (aq) + SO 4 2- (aq) 2Na + (aq) + 2Cl - (aq) + BaSO 2 (s) Ba 2+ (aq)) + SO 4 2- (aq) BaSO 2 (s) b) KCl and Na 2 SO 4 KCl(aq) + Na 2 SO 4 (aq) no reaction (both possible products are soluble, so there is no driving force for the reaction) c) Potassium hydroxide and cobalt(II) nitrate 2KOH(aq) + Co(NO 3 ) 2
