Solubility of NH4OH in Water

The video discusses the solubility of ammonium hydroxide (NH4OH) in water. It explains that according to solubility rules, compounds with the ammonium ion are soluble. A solubility table confirms that NH4OH is soluble. However, NH4OH does not exist as a solid compound; instead, ammonia (NH3) dissolves in water, partially dissociating into ammonium and hydroxide ions. The video concludes that NH4OH is soluble, but it always exists in dissociated form in water.
