Solubility of Ammonium Chloride

The video explores whether ammonium chloride (NH4Cl) is soluble in water. It confirms that NH4Cl is soluble by examining solubility rules, using a solubility chart, and suggesting a practical test. The video explains that NH4Cl dissociates into NH4+ and Cl- ions in water. It also notes that most ammonium and chloride compounds are soluble, except for silver chloride. The video concludes with a summary of the findings.
