You wish to use precipitation to separate Br− ion from I− ions in a solution that is 0.50 M in each. You find Ksp values for the copper(I) salts are 6.3 x 10−9 for CuBr and 1.3 x 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.
