Ionic Compounds and Bicarbonate

The video tutorial explains the composition and properties of sodium bicarbonate (NaHCO3), also known as sodium hydrogen carbonate. It describes NaHCO3 as an ionic compound consisting of a sodium ion and a bicarbonate ion. The tutorial details the ionic charges of these components, with sodium having a +1 charge and bicarbonate a -1 charge, resulting in a neutral compound. When dissolved in water, NaHCO3 dissociates into its constituent ions, making it soluble. The video concludes by summarizing the ions present in NaHCO3.
