| Lead Chloride, PbCl2 is only slightly soluble in water. You add 1 gram of lead chloride to 7 mL of water. Not all dissolves. If the Lead ion concentration at equilibrium is 0.001 M, calculate the Molarity of the Chloride ion in Solution.... |
Homework Answers
KSp of PbCl2 is 1.6 x 10^-5
PbCl2 <-----------> Pb^2+ + 2Cl-
Ksp = [Pb^2+][Cl-]^2
Ksp = x[2x]^2
1.6 x 10^-5 = 4x^3
x = 0.016 M
Thus, Molarity of chloride ion = [Cl-] = 2x = 2 x 0.016 = 0.032 M

Experiment 8 Solubility of lonic Precipitates Lead chloride is a slightly soluble salt. When lead chloride dissolves in pure water or an aqueous solution, the small quantity that dissolves completely ionizes and reaches equilibrium in a saturated solution, PbCl(s) ® Pb (aq) + 2Cl(aq) Kp = [Pb (C) (1) Lets be the molar solubility of lead chloride. In pure water, s = [Pb ) = (CH) / 2. In a solution containing Cl, a common ion to lead chloride, s...
