Silver chloride has Ksp=1.6x10^-10 and silver cheomate has Ksp=9.0x10^-12. We have 1.00 liter of a solution contains both nacl(0.10M) and Na2cro4(0.10M) solid AgNo3 is added slowly and the solution is stirred well.
a) which precipitate first Agcl or AgCro4?
B)what are the concentration of [Ag^+],[Cl-] and [CrO4^2-] at the point when the second salt just begins to precipitate?
C) is the method of selective precipitatation a good one for separating the anions in the solution?[hint calculate the percent of the fist ion (to precipitate) remaining in solution at the point the second anion begins to precipitate,in part (b) 99.5+% removed indicates good seperation!]

Inorganic Chemistry
Balance the molecular equations based on the reactions you mixed together and write the complete ionic equations and net ionic equations for all of the reactions that you tested that gave you a precipitate. if you got "no reaction" because you did not get a precipitate, then write the ionic equation by listing the ions for all the aqueous solutions on the reactant side and then an ---> and the words "no reactions".
AgNO3(aq) + KCl(aq) -----> KNO3 + AgCl
