Adding a complex ion forming species to a solution will increase the solubility of a slightly soluble species. Calculate the Molar solubility (s) of AgI in a 1.75 M ammonia solution. The Ksp for AgI is 8.3 x 10-17 and the Kf for Ag(NH3)2+ is 1.5 x 107. I have tried getting this but getting it wrong by following my class notes.
8.3 x 10-17* 1.5 x 107=1.245E-9
2.245E-9*3.5=4.3575E-9 than i took the sqrare root of it and got 6.601136266E-5 as my final answer but it is still wrong

Did you square 1.75 or multiply it by 2. I think you did the latter; you should have squared it.
