Select the false statement below.
A. PbCO3 is more soluble in aqueous HCl than in pure water
B. PbCl2 is less soluble in an aqueous solution of Pb(NO3)2 than inpure water
C. PbCl2 is less soluble in pure water than in aqueous KCN (Ksp ofPbCl2 = 1.7 x 10-5 and Kf of Pb(CN)42- = 2.0 x 1010)
D. PbCl2 is more soluble in aqueous HCl than in pure water
The theoretical solubility of calcium phosphate can be calculatedfrom its Ksp value, but its actual observed solubility is greaterthan its calculated theoretical solubility. Why?
A. hydrolysis involving the calcium ion acts to shift the calciumphosphate solubility equilibrium to the left, increasing thesolubility of the calcium phosphate
B. hydrolysis involving the phosphate ion acts to shift the calciumphosphate solubility equilibrium to the right, increasing thesolubility of the calcium phosphate
C. hydrolysis involving the calcium ion acts to shift the calciumphosphate solubility equilibrium to the right, increasing thesolubility of the calcium phosphate
D. hydrolysis involving the phosphate ion acts to shift the calciumphosphate solubility equilibrium to the left, increasing thesolubility of the calcium phosphate
E. hydration of the calcium ion produces an acidic solution whichresults in a greater solubility of calcium phosphate
