solution contains 0.25 M Ni(NO3)2 and 0.25 M Cu(NO3)2. A. Can the metal ions be separated by slowly adding Na2CO3 aq solution? Assume that for successful separation 99% of the metal ion must be precipitated before the other metal ion begins to precipitate, and assume no volume change on addition of Na2CO3 solution. Pls show step by step. Ksp of CuCO3 = 1.4 x10-10 Ksp of NiCO3 = 1.42X 10-7 B. If you need to redissolve the salt that was first precipitated, what
