What is the minimum concentration of AgNO3 that would cause a precipitation? (2 points) /3 e) A solution contains 0.25 M Ni(NO3)2 and 0.25 M Cu(NO3)2. The metal ions can be separated by slowly adding Na2CO3. Which salt precipitates out first? (NiCO3 Ksp = 1.4 x 10-7, CuCO3 Ksp = 2.5 x 10-10). Calculations need to be shown for full credit.
