Binary Acids are the first class of covalent acids

Binary Acids

Concept #1: Binary Acids represent covalent compounds containing a hydrogen ion and a non-oxygen anion.

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

a) HCNO                                  b) BaCl­2                                    c) HF                                        d) LiH 

Concept #2: A majority of binary acids are weak with exception to those containing some of the halogens.

Example #2: The following represent aqueous acid solutions. Identify the strong acid, weak acid and weakest acid.

Concept #3: The strength of binary acids is based on differences in electronegativity and atomic radius. 

Recall, as you move to the top right of the periodic table the electronegativity increases and the atomic radius decreases. 

Example #3: Which is the weakest acid from the following? 

a) HF                            b) HCl                           c) HI                             e) HBr                           d) All are equal. 

Example #4: Which is the weakest acid from the following? 

a) H2Se                         b) HF                            c) H2Te                         e) H2S                          d) All are equal 

Practice: Which of the following acids would be classified as the strongest? 

a) CH4                          b) H2Te                         c) H2S                           d) PH3                          e) BH3
