Question One

Question

The fictitious compound, pandemonium fluoride ( PnF2 ) has a Ksp value in water of 3.091x10^-9 M^3 at room temperature. Calculate the solubility of PnF2 in water. Express your answer in units of molarity.

Question Two

How would you expect the solubility of pandemonium fluoride to vary in water that is warmer than room temperature?

i)The solubility should not change, as the solubility is solely a property of the solute and solvent. It would be invariant with temperature.
ii)The solubility would likely decrease.
iii)The solubility would likely increase.

Answer 1

Why wouldn't you go about this problem the same was as for PbCl2?

Answer 2

Question One
9.17e-4

Question Two
iii)The solubility would likely increase.

Answer 3

Thank you
