Naming and Properties of HNO2

The video tutorial explains how to name HNO2 as nitrous acid using a flowchart and a common ion table. It begins by identifying the elements in HNO2 and determining their charges. The tutorial then guides viewers to find the NO2- ion in the common ion table, identifying it as the nitrite ion. Using naming rules, the tutorial shows how to convert nitrite to nitrous acid by replacing 'ite' with 'ous' and adding 'acid'. The video concludes with a summary of the naming process.
