Naming and Identifying Acids

This video tutorial from Chem Help ASAP covers the naming conventions for acids, focusing on both binary acids and oxyacids. It explains the rules for naming binary acids, which include using the 'hydro' prefix and '-ic' suffix, and provides examples like HCl and H2S. The tutorial then shifts to oxyacids, detailing how the suffixes '-ic' and '-ous' are used based on the polyatomic ion endings '-ate' and '-ite', respectively, with examples such as H2SO4 and HNO2. The video also demonstrates how to convert acid names back to their molecular formulas, emphasizing the importance of understanding charges and balancing them to achieve neutral compounds.
