You Wish to Use Precipitation to Separate Br^- Ion from I^-

question 106

Essay

You wish to use precipitation to separate Br^- ion from I^- ions in a solution that is 0.50 M in each.You find K_sp values for the copper(I) salts are 6.3 * 10^-9 for CuBr and 1.3 *10^-12 for CuI at 25°C.If you are required to reduce the value of one ion to 0.10% of its original value for "complete separation," will selective precipitation by Cu⁺ work? Show your calculations and justify your answer.
