Chemistry I have 250 mL of 0.250M Cd(NO3)2 that I mix with 500 mL of 0.100 M Cu(NO3)2 and 250 mL of 0.050 Fe(NO3)2. A) If I start adding K₂CO3 (s) to the mixture, how many grams do I need to add before the first precipitate forms? B) How much of the first cation is left in solution when the second cation begins to precipitate? C) How efficient was your separation of the first cation (% precipitated)?
