NAMING COMPOUNDS

6.4 - Binary Acids

Acids are hydrogen-containing compounds that yield hydrogen ions (H⁺) in water. Binary acids are acids that consist of two elements, one of the elements hydrogen-containing compounds. As the pure compound (ie- in the gaseous or liquid state), they have different properties than they do in aqueous solution of the compound. The rules for naming the acid as the pure compound is different for naming the acid in aqueous solution.

Here are some examples of binary acids:

Rules for naming binary acids:

1. As the pure compound (ie - in the gaseous or liquid state),
   • start with 'hydrogen'
   • follow by the anion name ending in '-ide'.
2. As aqueous acid solutions,
   • start with 'hydro-'.
   • change the anion name to end with '-ic'.
   • add the word 'acid' at the end.

Let's apply the above rules and name the above examples. Click on each formula to check the name of each compound.
