Is PbI2 soluble in water or not? Following the solubility rules for ionic compounds, salts containing Pb are insoluble and iodide salts are soluble, so can it be both?

  1. No. I don't know what chart you are looking at but not all Pb salts are insoluble. PbI2, PbBr2, and PbCl2 are insoluble as are a number of other Pb salts. Pb(NO3)2, for example, is soluble.
