Sodium fluoride and lead nitrate are both soluble in water. If 1.13 g of NaF and 0.232 g of Pb(NO3)2 are dissolved in sufficient water to make 1.00 L of solution, will a precipitate form? How do you know if there should be a precipitate or not? What is the chemical formula for the possible precipitate? Look in your textbook for any necessary equilibrium constants.
