A basic solution contains the iodide and phosphate ions that are to be separated via selective precipitation. the i– concentration, which is 9.00×10-5 m, is 10,000 times less than that of the po43– ion at 0.900 m . a solution containing the silver(i) ion is slowly added. answer the questions below. ksp of agi is 8.30×10-17 and of ag3po4, 8.90×10-17.

The given question is incomplete. The complete question is as follows.

Calculate the minimum concentration required to cause precipitation of AgI.

Explanation:

It is known that at the stage of precipitation, the is equal to the ionic product.

Therefore, expression for for is as follows.

In the given case,

Hence,

                       =

                       =

Now, for the expression for will be as follows.

or,      

                     =

                     = M
