Solubility of Lead(II) Carbonate

The video tutorial explores the solubility of lead(II) carbonate (PbCO3) in water, concluding that it is insoluble. The instructor explains this using three methods: solubility rules, a solubility chart, and a practical test. The solubility rules indicate that most carbonates are insoluble, with lead not being an exception. The solubility chart confirms this by showing that PbCO3 does not dissolve in water. A practical test further supports this conclusion, demonstrating that PbCO3 remains undissolved in water. Despite a minimal amount dissolving, for practical purposes, PbCO3 is considered insoluble.
