2)c. Lead (II) fluoride solid is an interesting species in that it is sparingly soluble in pure water. If the solubility constant Ksp for PbF2 is Ksp = 2.7 x 10-8
PbF2 (s) <------>Pb2+ (aq) + 2F- (aq) Ksp = 2.7 x 10-8
i. Determine how many grams of PbF2 can dissolve in 200.0 mL of water (4 Marks)
ii. If you have a 500.00 mL solution containing 0.01 moles of Pb2+ and 0.1 moles of F- ions, will a precipitate of PbCl2 solid form? (3 Marks)
iii. What will be the molar solubility of PbF2 in 0.1M Pb(NO3)2 solution (3Marks)
1)Uranium oxide reacts with hydrogen fluoride according to the equation
UO2 (s) + 4HF (g) <------->UF4 (g) + 2H2O (g) ÎH = - 256 kJ
If you have equal number of moles (0.1 moles) of reactants and products in (a) above, determine which direction the equilibrium will shift if Keq = 10,
