Solubility of Carbonates in Water

The video explores the solubility of barium carbonate (BaCO3) in water, concluding that it is insoluble. Three methods are discussed: memorizing solubility rules, using a solubility chart, and conducting a practical experiment. The solubility rules indicate that most carbonates are insoluble, with exceptions for Group 1 and ammonium ions. The solubility chart confirms barium carbonate's insolubility. A practical test would show that barium carbonate does not dissolve significantly in water.
