Detailed explanation-1: –ate and-ite are commonly used for polyatomic ions of Oxygen.-ate is used for the ion that has the largest number of Oxygen atoms. The-ite would be used for the ion with the smaller. NO2 and NO3 are known as Nitrite and Nitrate respectively.
Detailed explanation-2: -Naming Polyatomic Ions The name of the ion usually ends in either-ite or-ate. The-ite ending indicates a low oxidation state. Thus, the NO2-ion is the nitrite ion. The-ate ending indicates a high oxidation state.
Detailed explanation-3: -Anions in this group containing oxygen are referred to as oxyanions and are all named with an-ate or-ite ending.
Detailed explanation-4: -B. If the acid contains an oxygen, determine the name of the polyatomic anion. If the anion ends in “-ite” then the ending “-ous” is used.
Detailed explanation-5: -Suffixes are used based on the ending of the original name of the oxyanion. If the name of the polyatomic anion ended with-ate, change it to-ic for the acid and if it ended with-ite, change it to-ous in the acid.
