1. To Name Acids with Simple Anions:

• The first part of the name is the prefix hydro.


• This is followed by a the name of the simple anion, which is shortened and - ic added
  
  
  
  • for example chlorine (Cl-) would become chloric
  
  
  
  


• The last part of the name is the word acid

2. To Name Acids with polyatomic anions:

• The first part of the name is the name of the anion which is shortened . One of two suffixes added to this name.
  
  
  
  • - ic if the anion name ends in - ate.
  
  
  • - ous if the anion name ends in - ite.
  
  
  
  


• The last part of the name is acid

3. To determine an acid formula from a name (Using a table of ions ) we:

1. Determine the anion present from the name.


2. Since the compound is an acid the cation ( positive ion ) is H +


3. Write down the formulas of the two ions . Make the value of the charge on the negative ion the subscript on the hydrogen ion

Example:

Sulfuric Acid

• sulfuric ------> sulfate --------> SO₄ ^2-


• acid -------> hydrogen --------> H ⁺¹


• Formula -------> H₂SO₄
