Question 1

A solution contains 0.018 moles each of I–, Br–, and Cl–. When the solution is mixed with 200 mL of 0.24 M AgNO3, how much AgCl(s) precipitates out?
 
Ksp
AgI
 
= 1.5 × 10–16
 
Ksp
AgBr
 
= 5.0 × 10–13
 
Ksp
AgCl
 
= 1.6 × 10–10


◦ 0.0 g
◦ 1.7 g
◦ 2.6 g
◦ 3.3 g
◦ 5.0 g

Question 2

A solution is 0.010 M in each of Pb(NO3)2, Mn(NO3)2, and Zn(NO3)2. Solid NaOH is added until the pH of the solution is 8.50. Which of the following statements is true?
Salt
Ksp
Pb(OH)2
1.4 × 10–20
Mn(OH)2
2.0 × 10–13
Zn(OH)2
2.1 × 10–16


◦ No precipitate will form.
◦ Only Pb(OH)2 will precipitate.
◦ Only Mn(OH)2 will precipitate.
◦ Only Zn(OH)2 and Pb(OH)2 will precipitate.
◦ All three hydroxides will precipitate.
