A: What is the concentration of iodide ions in a saturated solution of PbI2?

B: What is the solubility of PbI2 in a 0.010M solution of NaI?

##### 1 Answer

**Part- A**

If the concentration of

So

So the concentrattion of

**Part- B**

Let the solubility of

Then in this case

And

So

neglecting

So solubilty of
