The question is:

If a solution containied a mixture of Ba2+ and Ag+ ions, write a short experiemental procedure that would allow the two ions to be separated and includes a confrimatory test for verifying the presence of each ion.

I\'m not exactly sure where to start, so any help would be appreciated! Thank you!!

Solution

If you add some chloride (Cl-) ions to the solution and a precipitate forms, this tells

you that the unknown ion is Ag+ and not Ba2+. (NOTE: Remember that

the ion is either Ag+ or Ba2+ and not something else! Analyzing a solution when you have no idea what

ions are in it is a long complicated procedure involving many steps!)

Notice that chloride, bromide and iodide all act the same with these positive ions, so we could have added either chloride, bromide or iodide to get the same results.
