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?

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.

According to the solubility rules for ionic compounds, most lead (Pb) salts are considered insoluble in water. However, there are a few exceptions to this rule, and PbI2 happens to be one of them.

PbI2, or lead(II) iodide, is actually a soluble salt. This means that it can dissolve in water to form a homogeneous solution.

So, in summary, PbI2 is soluble in water, despite the general rule that salts containing Pb are insoluble.

According to the solubility rules for ionic compounds, salts containing Pb (lead) are generally insoluble in water. However, when it comes to iodide salts, they are usually soluble in water. So, considering these rules, it may seem contradictory. However, in this case, lead iodide (PbI2) is an exception.

Lead iodide (PbI2) is actually considered slightly soluble in water. It forms a sparingly soluble salt, meaning that only a small amount of it dissolves in water.

To determine the solubility of PbI2, it is always best to consult a reliable source such as a solubility chart or a database that provides accurate information. These resources usually list the solubility of various compounds, including lead iodide.

Alternatively, you can perform a simple experiment to check the solubility by adding a small amount of PbI2 to water and observing whether it dissolves completely or forms a precipitate.

Remember that there are exceptions to the solubility rules, so it's always a good practice to refer to reliable sources or perform experiments for specific compounds like lead iodide.
