Silver ion is being considered as a reagent to separate I - from SCN in solution i.e. 0.060 M in KI and 0.070 M in NaSCN, KSP AgSCN = 1.10-12, Ksp AgI = 1.10-16

a) What concentration is required for Ag+ to lower the concentration I - concentration to 1.0 X 10-M6

b) What is the Ag+ concentration of the solution when AgSCN starts to precipitate?

c) What is the ratio of SCN to I - when AgSCN starts to precipitate?

d) What is the ratio of SCN to I - when the concentration of Ag+ is 1.0 X 10-3 M
