Naming Acids and Ions

The video tutorial explains how to name the acid HClO2 using a flowchart and a common ion table. It begins by identifying the components of HClO2, recognizing it as an acid due to the presence of hydrogen. The polyatomic ion ClO2- is identified, and its charge is determined. The tutorial then demonstrates how to look up ClO2- in the common ion table, identifying it as the chlorite ion. Using the flowchart, the video shows how to convert the name from chlorite to chlorous acid by replacing 'ite' with 'ous' and adding the word 'acid'. The tutorial concludes with the final name, chlorous acid, and a thank you from Dr. B.
