Given 100 mL of a solution that contains 0.80 mM Ag* and 0.80 mM Cu*, can the two metals be separated by selective precipitation as the insoluble bromide salts by adding 100 mL of an 8.0 mM solution of KBr? Ksp values are 6.27 x 10-9 for CuBr and 5.35 x 10 13 for AgBr. Yes, the two metals can be separated. No, the two metals cannot be separated.
