Here are many example problems for naming acids. In order to name an acid, you need to break it down into the ions that make it up. One ion is H+ and the other is a negative ion, which may be a polyatomic ion. Based on the name of the negative ion, there are different rules for how to name the acid. IDE becomes HYDRO- -IC Acid, ATE becomes -IC Acid, and ITE becomes -OUS Acid. There are also some important exceptions: Phosphoric Acid, Phosphorous Acid, Sulfuric Acid, and Sulfurous Acid. The acids that we will name in this video are Perbromic Acid, Arsenous Acid, Boric Acid, Hydrofluoric Acid, Phosphorous Acid, and Hypoiodous Acid.
