Properties and Characteristics of NaOH

The video tutorial explains how to name the compound NaOH, sodium hydroxide. It begins by identifying NaOH as an ionic compound composed of a metal (sodium) and a polyatomic ion (hydroxide). The tutorial details the process of determining the charges of sodium and hydroxide ions, using the periodic table and common ion table. It concludes by naming the compound sodium hydroxide and highlighting its property as a strong base.
