Ammonium Sulfate Bonding and Properties

The video explores whether ammonium sulfate (NH4)2SO4 is ionic or covalent. It concludes that while the compound is overall ionic, it contains covalent bonds within its polyatomic ions. The ammonium ion (NH4+) and sulfate ion (SO4^2-) interact to form an ionic bond, resulting in a net charge of zero. The video also explains that within each polyatomic ion, covalent bonds hold the atoms together. When dissolved in water, ammonium sulfate separates into its constituent ions due to its ionic nature.
