Solubility of Iron III Phosphate

The video explores whether iron III phosphate (FePO4) is soluble in water, concluding it is insoluble. It discusses solubility rules, highlighting that most phosphates are insoluble except for a few exceptions, which do not include iron III phosphate. A solubility chart is used to confirm this, showing that FePO4 is insoluble. Although a small amount may dissolve, it is negligible. The video suggests a practical experiment to test solubility by adding FePO4 to water. Overall, the video provides a comprehensive understanding of the solubility of iron III phosphate.
