  1. Acid/Base review

  2. In an acid/base titration, one has an equal amount of acid and base1) at the beginning of the titration.2) after all the base has been added.3) all the time throughout the titration.4) at the middle of the large change of pH during the titration.

  3. When an acid reacts with a base what compounds are formed?1) Only salts. 2) Water only.3) A salt and water. 4) Metal oxides.

  4. Acids generally release hydrogen gas (H2) when they react with1) non-metals. 2) gold.3) metals4) limestone rock.

  5. The math definition of pHis1) -log[H+]. 2) -log[OH-].3) log[H+]. 4) log[OH-].

  6. Which is a property that you could use to identify a base in the lab?1) A sour taste. 2) It would be a non-electrolyte.3) It would react with metals. 4) It feels slippery.

  7. Which is a property that you could use to identify an acid in the lab?1) A sour taste.2) It would be a non-electrolyte.3) It would not react with other substances. 4) It feels slippery.

  8. What is an Arrhenius acid?1) A substance that increases the hydroxide ion concentration; [OH-].2) A substance that makes a solution salty.3) A substance that does not break up into ions in solution.4) A substance that increases the hydrogen ion concentration; [H+].

  9. Hydroxides of group I metals (Remember, group I metals are elements on the periodic table.) are1) salts. 2) non-electrolytes.3) bases.4) acids.

  10. If the [H+] of a solution is greater than the [OH-], the solution is1) basic. 2) salty.3) neutral 4) acidic.

  11. Which of the following solutions is the most basic?1) [H+] = 1X10-2 M. 2) [H+] = 1X10-11 M.3) pH = 3 4) pH = 7

  12. If the hydrogen ion, the [H+], is equal to 1X10-10, the solution is1) acidic. 2) basic.3) neutral (like water). 4) tastes salty.

  13. Acids, when placed on litmus paper, turn it1) blue. 2) red.3) magenta. 4) clear.

  14. If the pH of a solution is 8.0, the solution is1) basic.2) acidic.3) neutral. 4) a salt solution.

  15. Compounds that are electrolytes are1) acids. 2) bases.3) salts. 4) all of these are good answers.

  16. The pH of an acidic solution is1) less than 0. 2) greater tan 7.3) less than 7.4) greater than 14.

  17. The reaction: HCl + KOH → KCl + H2O is 1) a single replacement reaction.2) an acid/base reaction.3) a synthesis reaction. 4) a combustion reaction.

  18. T/F Acids bubble when they are placed on a metal. The gas produced is CO2

  19. T/F An Arrhenius base will increase the OH- ions in solution.

  20. T/F Acids taste sour.

  21. T/FIn a double replacement reaction, only the spectator ions are shown in the equation.

  22. T/F Acids turn litmus blue.

  23. T/F A BrØnsted acid will always produce OH- in its solution.

  24. T/FStrong acids break down completely into ions in solution.

  25. T/F Salts can be formed by an acid/base neutralization reaction; they are the spectator ions that remain after that reaction has taken place because they are electrolytes.

  26. T/F For basic solutions, the [H+] is less than 1X10-7.

  27. T/F A base is dissolved in water. The resulting solution will have a OH- concentration equal to the H+ concentration for that solution.
