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.

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.

Page 4: Acid/Base review

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

Page 5: Acid/Base review

The math definition of pH is1) -log[H+].2) -log[OH-].3) log[H+].4) log[OH-].

Page 6: Acid/Base review

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.

Page 7: Acid/Base review

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.

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+].

Page 9: Acid/Base review

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

Page 10: Acid/Base review

If the [H+] of a solution is greater than the [OH-], the solution is1) basic.2) salty.3) neutral4) acidic.

Page 11: Acid/Base review

Which of the following solutions is the most basic?1) [H+] = 1X10-2 M.2) [H+] = 1X10-11 M.3) pH = 34) pH = 7

Page 12: Acid/Base review

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

Page 13: Acid/Base review

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

Page 14: Acid/Base review

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

Page 15: Acid/Base review

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

Page 16: Acid/Base review

The pH of an acidic solution is1) less than 0.2) greater tan 7.3) less than 7.4) greater than 14.

Page 17: Acid/Base review

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.

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

Page 19: Acid/Base review

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

Page 20: Acid/Base review

T/F Acids taste sour.

Page 21: Acid/Base review

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

Page 22: Acid/Base review

T/F Acids turn litmus blue.

Page 23: Acid/Base review

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

Page 24: Acid/Base review

T/F Strong acids break down completely into ions in solution.

Page 25: Acid/Base review

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.

Page 26: Acid/Base review

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

Page 27: Acid/Base review

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