Solubility of Iron II Carbonate

The video explores the solubility of iron II carbonate (FeCO3) in water. It discusses three methods to determine solubility: memorizing solubility rules, using a solubility chart, and conducting a practical test. According to solubility rules and charts, iron II carbonate is generally insoluble in water, with exceptions for group 1 elements and ammonium ions. A practical test would confirm this, as the compound would not dissolve significantly in water.
