Bases represent compounds that neutralize acids when mixed

Strong & Weak Bases

Concept #1: A strong base can be formed when a Group 1A and some Group 2A metals combine with certain basic anions.

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

a) Be(OH)2                                 b) NaO2                                         c) LiNH2                                        d) Mg(OH)2                   e) KIO

Concept #2: Strong Bases represent strong electrolytes and weak bases represent weak electrolytes.

Example #2: Which of the following bases will partially dissolve when placed in water? 

a) LiOH                         b) NaNH2                      c) Al(OH)3                     d) Cs2O                        e) KOH

Concept #3: Amines represent a class of covalent compounds that can be either acidic or basic based on their charge.

Example #3: Identify the amine that will weakly accept a proton (H+) when in the presence of an acid. 

a) H2NNH3+                   b) (CH3)2NH                  c) CH3SH                      d) CH3NH3+                   e) CH3CH2CH3 

Practice: Which of the following bases would more greatly favor the product side of a chemical reaction? 

a) BeH2                         b) H2Se                         c) SrH2                          d) Pb(OH)4                    e) HF

Practice: Which of the following compounds would be found as mostly molecules when placed into water? 

I. Be(OH)2                     II. HNO3                        III. LiOH                        IV. (CH­3)2NH                 V. CaO

a) I, IV, V

b) I only

c) I and IV

d) IV only

e) None of the above
