Acids are compounds, usually ionic, which have H+ as the cation Naming Acids Acids are compounds, usually ionic, which have H+ as the cation

Inorganic Acids Can be grouped into two types Binary and Oxoacids

Binary Acids Contain only two different elements One of them is H+ and the other is an anion To name them: 1) Take the anion root word, put hydro in front of it 2) Change the ending from -ide to -ic Acid Example: HCl is H+ with a chloride Cl- ion. The name is Hydrochloric Acid HBr Hydro + brom + ic Acid

Oxoacids Acids whose anions are polyatomic anions that contain oxygen. H+ is still the cation. To name them: Change the –ate ending of the anion to –ic Acid OR change the –ite ending of the anion to –ous Acid Examples: HNO3 This is H+ with the nitrate (NO3-) ion Nitric Acid HNO2 This is H+ with the nitrite (NO2-) ion Nitrous Acid

Organic Acids Contain carbon Except for carbonic acid, which is considered inorganic. Their naming system is basically the same as the oxoacids The one that you need to know is Acetic Acid (vinegar): CH3CO2H or sometimes written CH3COOH. This is a H+ with the acetate (CH3CO2-) ion.
