Silver ion is being considered for separating Ifrom SCNin a solution that is 0.075M in KI and 0.060M in NaSC (Ksp(AgI)=8.31017,Ksp(AgSCN)=1.11012) a. What Ag+concentration is needed to lower the Iconcentration to 2.0106M ? Concentration = M b. What is the Ag+concentration of the solution when AgSCN begins to precipitate? Concentration = c. What is the ratio of SCNto Iwhen AgSCN begins to precipitate? (Simplify your answer completely.) I[SCN]= d. What is the ratio of SCNto Iwhen the Ag+concentration is 2.5103M ? (Simplify your answer completely.) [I][SCN]=
