Intro to Bases

Concept #1: A base can be classified as either ionic or covalent.

Example #1: Which of the following represents the possible structure of a base?

a) C(OH)4                                  b) NH4+                                     c) KOH                                     d) HC2H3O2

Concept #2: A base is any substance that ionizes into basic anions, is slippery to the touch, bitter to the taste and alters litmus paper.

Example #2: Which of the following is a characteristic of a strong base? 

a) It turns blue litmus paper red. 

b) It releases H+ ions in a solution. 

c) It removes OH ions in a solution. 

d) It can be used in the production of cleaning supplies.

Practice: Which of the following compounds will turn a piece of red litmus paper to a bluish color? 

a) HI                                         b) C6H5NH2                               c) CH3COOH                            d) HOCN
