Sodium Nitrate and Aqueous Reactions

The video explains the reaction between sodium nitrate (NaNO3) and water (H2O). It describes sodium as a metal and nitrate as a polyatomic ion, forming an ionic compound. The video details how to find the charges of Na+ and NO3- ions using the periodic table and a polyatomic ion table. It then explains the dissolution of solid NaNO3 in water, resulting in an aqueous solution of Na+ and NO3- ions. The video concludes with writing the chemical equation for the reaction and omitting water on the product side due to the aqueous state.
