Solubility of Ammonium Nitrate

The video explores whether ammonium nitrate (NH4NO3) is soluble in water, confirming that it is highly soluble. Three methods are used to determine this: solubility rules, a solubility chart, and a practical test. The solubility rules indicate that compounds with ammonium (NH4) and nitrate ions are soluble. The solubility chart further supports this, showing that both ammonium and nitrate compounds are generally soluble. Finally, a practical test is suggested, where NH4NO3 is dissolved in water, dissociating into NH4+ and NO3- ions, confirming its solubility.
