Using 1.0x10-6 M as the quantitative precipitation criterion, if silver ions are added to a solution containing initiall

[answerhappygod]

Using 1.0x10-6 M as the quantitative precipitation criterion, if
silver ions are added to a solution containing initially 0.050 M I-
and 0.080 M SCN- ions, which of the following statement is correct
related to the (i)which ion precipitates first, and the molarities
of Ag+ required (ii)to decrease the concentration of the first
precipitated ion to 1.0x10-6 M and (iii)to initiate the
precipitation of the second ion? (for AgI Ksp =8.3x10-17, for AgSCN
Ksp =1.1x10-12)
