Question 1

What ratio of [NH4+]/[NH3] would provide a buffer of pH low enough to avoid precipitation of Co(OH)2(s) from a 0.50 M Co2+(aq) solution? (Kb for NH3 = 1.8 × 10-5 and Ksp for Co(OH)2= 2.0 × 10-14
◦ 1/50
◦ 1/90
◦ 1/1
◦ 90/1
◦ 50/1

Question 2

When 100 mL each of 2.0 × 10-4 M Ag+(aq) and 2.0 × 10-1 M CO32-(aq) are mixed, what is the remaining Ag+(aq) ion concentration and is precipitation complete?  The solubility product constant of Ag2CO3(s) is 8.5 × 10-12.
◦ 4.2 × 10-8 M, yes
◦ 2.0 × 10-4 M, no
◦ 9.2 × 10-6 M, no
◦ 1.0 × 10-3 M, no
◦ 8.5 × 10-9 M, yes
