I need help with this question please help, I just don't understand it
Fe3+ (aq), Ca2+ (aq) and Ba2+ are all present in the same solution. Fully describe a procedure whereby you could separate these ions from one another
Mr Pursley posted this response, but I don't understand and I have a test this week and its worth 20%. Thanks

look at your solubility chart
Check your chart with this:
what happens if you make the OH ion strong? Doesnt that precipated the Ca, and Fe? filter those off, leaving the Ba ion in the solute.
Add water to the filtrate, add just a tad of sulfuric acid to dissolve one, and the other does not dissolve (check your chart).

It appears to me that the directions are clear. What do you not understand about Bob Pursley's response?
