Strong 3. True 4. True 5. Weaker 6. Strong 7. Ka is a measure of the strength of an acid. The larger the Ka value (greater than one), the stronger the acid. 8. Kb is a measure of the strength of a base. The larger the Kb value (greater than one), the stronger the base 9. The reverse of neutralization. In hydrolysis, a salt and water, form the parent acid and parent base 10. Despite having the same concentrations, vinegar (acetic acid), does NOT ionize (throw H+ ions into water) to the same EXTENT that HCl does, and therefore is considered a weaker acid. 11. True. To be considered a strong acid, you must ionize to a great extent or almost completely. The more free-flowing ions, the better you conduct electricity, so the stronger the electrolyte 12. see answer to Question 19 from the first review packet Answers AB #4 Hydrolysis 13. neutral 14. acidic 15. basic 16. can’t predict 17. 2. HNO3 = a Strong Acid (one of the top 5 strongest AND it has a very large Ka) 3. H3PO4 = a somewhat weak acid (one of the “stronger, weaker acids…nearer the top of the Ka ref table) 4. K2CO3 = a salt (an ionic compound with a + ion other than H+ and a negative ion other than OH-. It is basic salt because its parent base, KOH is a strong base, while its parent acid is carbonic acid, a weak acid 5. Mg(OH)2 = a base from Group llA …lets call it strong. 6. LiNO3= a salt (same reason as in #4) BUT this is a NEUTRAL salt because its parent base is LiOH ( a strong base) and its parenmt acid is HNO3, nitric acid, one of the top 5 strong acids 7. HC2H3O2= acetic acid or vinegar. It’s a weak acid …Ka is small …1.8 x 10^-5 at 25C. 8. NaC2H3O2= a basic salt because its parent base is NaOH, a strong base, and its parent acid is vinegar, a weak acid 9. Al2(SO4)3= an acidic salt because its parent acid is sulfuric acid, H2SO4, a strong acid, and its parent base is Al(OH)3, a weak base (Al is NOT a metal from Group l! or 11A) 10. ZnSO4= an acidic salt because its parent acid is sulfuric acid, H2SO4, a strong acid, and its parent base is Zn(OH)3, a weak base (Zn is NOT a metal from Group l! or 11A)
