Question

S. How is the solubility of the following compounds affected in an acidic solution? a. Mg(OH)2 o Increases o Decreases o Not affected b. PbCO o Increases o Decreases o Not affected c. Agl o Increases o Decreases o Not affected 6. The molar solubility of Pb0) in a 0.10 M/NalO, solution is 2.4 x 10'" mol/L. What is Ksp for Pb(IOs) Which of the following ionic compounds will be more soluble in acid solution than in water? (More than one correct answer.) 7. (a) BaSO4 (b) PbCl2 (c) Fe(OH)s (d) CaCO 8. Calculate the molar solubility of Fe(OH2 in a solution buffered at pH of 9.00 The solubility product of Mg(OH)2 is 1.2 x 10". what minimum or concentration must be attained (for example, by adding NaOH) to decrease the Mg solution of Mg(NOs)h to approximately 1.0x 10 1 Mr 9. concentration in a 1.0 x 10-10 vng

Explanation / Answer

a)

Mg(OH)2 incrases since H+ and OH- react

b)

PBCO3; increases since CO3-2 + H+ react to form H2CO3

c)

AgI; no effect
