Given a description of a solution of two components, identify the solute and the solvent. 2. Write a description of the process for dissolving an ionic compound in water. Your description should include mention of the nature of the particles in solution and the attractions between the particles in the solution. 3. Given the formula for an ionic compound, predict whether it is soluble in water or not. 4. Given formulas for two ionic compounds, (1) predict whether a precipitate will form when the water solutions of the two are mixed, (2) if there is a reaction, predict the products of the reaction and write their formulas, and (3) if there is a reaction, write the complete, complete ionic, and net ionic equations that describe the reaction. 5. Describe precipitation reactions. Your descriptions should include mention of the nature of the particles in the system before and after the reaction, a description of the cause of the reaction, and a description of the attractions between the particles before and after the reaction. 6. Write a description of the process for the solution of a strong monoprotic acid, sulfuric acid, and a weak monoprotic acid in water. 7. Identify the following as strong monoprotic acids: HCl, HBr, HI, HNO 3 , and HClO 4 . 8. Identify sulfuric acid, H 2 SO 4 , as a strong diprotic acid. 9. Given a formula for any acid, identify it as a strong or weak acid. 10. Write a description of the process for the solution of ammonia, NH 3 , in water. 11. Given the formula or name of a compound, classify it as a strong electrolyte, weak electrolyte, or nonelectrolyte. 12. Given a formula for an ionic compound, identify it as representing a weak base, a strong base, or a substance that is neutral in the Arrhenius acid-base sense. 13. Identify the following as anions that are neutral in the acid-base sense: Cl − , Br − , I − , NO 3 − , and ClO 4 − . 14. Identify the following anions as weak acids: hydrogen sulfate ion, HSO 4 − , and dihydrogen phosphate ion, H 2 PO 4 − . 15. Identify ammonia as an uncharged, weak base. 16. Identify ionic compounds containing hydroxide ions as strong bases. 17. Given the pH of a solution, identify the solution as acidic, basic, or neutral. 18. Given the pH of two acidic solutions, identify which solution is more acidic. 19. Given the pH of two basic solutions, identify which solution is more basic. 20. Describe how litmus paper can be used in the laboratory to identify whether a solution is acidic or basic. 21. Write a description of the process that takes place at the molecular level when a strong acid reacts with an aqueous strong base. Your descriptions should include mention of the nature of the particles in the system before and after the reaction, a description of the cause of the reaction, and a description of the attractions between the particles before and after the reaction. 74 Chapter 5 Chemical Reactions...
