A student want to prepare a saturated solution of Ag+ ion. He has got three samples AgCl (Ksp = 10–10), AgBr (Ksp = 10–13) and Ag2CrO4 (Ksp = 10–12). Which of the above compound will be used by him using minimum weight to prepare the saturated solution?
(a) AgCl
(b) AgBr
(c) Ag2CrO4
(d) All of these
