Quiz on polyatomic ions today, followed by acid naming – if you missed it you must make it up tomorrow! (If you’re still out tomorrow you’ll be taking a different quiz).
Acids
Learned the rules for naming acids. If the acid does not contain oxygen, it is named hydro_______ic acid, where the root of the other element/ion in the compound goes in the middle. Ex: HCl = hydrochloric acid.
If the acid contains oxygen, then determine the polyatomic ion in the name. If the polyatomic name ends in -ate, change it to -ic and add “acid.” If the polyatomic name ends in -ite, change it to -ous and add “acid.” Ex: HNO3 –> NO3- is nitrate –> nitric acid. HNO2 –> NO2- is nitrite –> nitrous acid.
