Consider the solubility of lead (II) chloride,
The equilibrium constant, Ksp, is 1.2 × 10−5. If 100 mL each of 0.02 M KCl and 0.02 M Pb(NO3)2, both strong electrolytes, are mixed together, what will take place?
1. A precipitate of PbCl2 would form.
2. No precipitate would form.
3. There is not enough information.
4. A precipitate of KNO3 would form.
