Asolution is 0.10 m in pb(no3)2 and 0.10 m in agno3. solid nai is added until the second solid compound is on the verge of precipitating.
which compound precipitates first and what is the i- concentration when the second compound begins to precipitate? ksp for agi is 1.5 x 10-16 ksp for pbi2 is 8.7 x 10-9pbi_2,\: 5.9\times10^{-4}\: m
pbi_2,\: 4.4\times10^{-3}\: m
agi,\: 2.9\times10^{-4}\: m
agi,\: 9.3\times10^{-5}\: m
agi,\: 8.7\times10^{-8}\: m
