Ksp for PbCl2(s) is 1.6 x 10-³. If you mix 200.0 mL of 0.010 M Pb(NO3)2(aq) with 400.0 mL of 0.010 M NaCI(aq), then
sodium nitrate will precipitate.
the concentration of CI will be 0.0033 M.
no precipitate will form.
PbCl2(s) will precipitate.
Sodium chloride is added slowly to a solution that is 0.010 M in Cu+, Ag+, and Au+. Because solubility "rules" are generalizations, we don't use solubility rules when we have the specific Ksp data available. Instead, here, we can just use the Ksp value for CuCl which is 1.9 × 10–7, for AgCl is 1.6 × 10–10, and for AuCl is 2.0 × 10–13. Based on these specific Ksp values, which compound will precipitate first?
All will precipitate at the same time.
It cannot be determined.
CuCl(s)
AgCl(s)
AuCl(s)
I need help with Table 11-1. but I need something sorted so I can understand the answer.
