Solubility of Barium Sulfate

The video explores the solubility of barium sulfate (BaSO4) in water, concluding that it is insoluble. It discusses three methods to determine this: consulting solubility rules, using a solubility chart, and conducting a practical test. The solubility rules indicate that while most sulfates are soluble, barium sulfate is an exception. The solubility chart confirms this by showing barium sulfate as insoluble. Finally, a practical test would show that barium sulfate does not dissolve in water, aligning with the rules and chart findings.
