Title: How is it possible to separate ions of Ca^2+ and Ba^2+ from a solution?
Post by: peyuh228 on January 04, 2023, 09:34:16 AM
I tried googling this question and one possbile answer was that I should add aqueous sodium sulfide to the solution, however I am not sure if it is correct, as both products (i.e., calcium sulfide and barium sulfide) are soluble. Am I missing something?

The soloubilities are different of Ca, Sr and Ba salts.  There are measure for separation by cristallisation.

Work on Ksp (solubility product) to understand these type of questions.
