Module 5—Acids and Bases
Reflect and Connect
In this lesson you learned about strong and weak acids and polyprotic acids and bases. Below are two incomplete tables summarizing information presented in this lesson.
Examine these tables. Copy these tables into a separate word-processing document. Using a different colour of text, add additional information to each of these tables. Choose information that you think will be helpful in recalling the information presented in this lesson. The information you add may include definitions, clarifying statements including chemical equations, and examples.
Place a copy of your final versions of these tables into your course folder.

Definition |
a substance that forms a solution with strong acidic properties |
a substance that forms a solution with weak acidic properties
Weak acids react incompletely with water (<50%). |
a substance that forms a solution with strong basic properties
Strong bases are ionic hydroxides. |
a substance that forms a solution with weak basic properties
Weak bases react partially with water. |

Monoprotic Acid |
Polyprotic Acid |
Monoprotic Base |
Polyprotic Base |
Definition |
an acid that possesses only one ionizable proton |
an acid with more than one acidic hydrogen available to react with water to produce hydronium ions |
a base that can react only once with water to produce hydroxide ions |
a base that can react more than once with water to form hydroxide ions |
Examples |
HCl(aq) |
HOOCCOOH(aq) |
