The video explores the solubility of barium hydroxide (Ba(OH)2) in water, highlighting its classification as slightly soluble according to solubility rules, but also as soluble when consulting solubility charts. Despite its limited solubility, barium hydroxide is considered a strong base because the portion that dissolves dissociates completely into Ba2+ and OH- ions. The video concludes by comparing barium hydroxide's solubility to more soluble compounds like sodium nitrate.
