21ya i too felt this questn was missi sumthin!!
but this was my BITSAT questn :'(
this is not fair!! :'(
Ksp AgCl = 1.7 x 10-10
Ksp AgI = 8.3 x 10-17
both AgCl and AgI are taken in solid form and shaken with water in a bottle....
Find the concn. of I- in solution once equilibrium is reached
dont rem the options :(

1357xz=1.7×10-10
yz=8.3×10-17
x+y=z (charge balance)
Is anything else required?
1tapan..at best v can only find the ratio of I- to Cl- ..not their individual concentrations fr the given info.
so Cl- conc needs to be given..
Cl- : I- = Ksp1 : Ksp2

1hey meh 2 gt this q........ i 2 left
i gt 2 more q's wich wer ambiguis
62xz=1.7×10-10
yz=8.3×10-17
x+y=z
is this that tough!!
x(x+y)= a
y(x+y) = b
(x+y)2=a+b
x+y=√a+b
x=a/√a+b
similarly,
y=b/√a+b
solved :P
