In the laboratory you are given the task of separating
Ba2+ and
Ag+ ions in aqueous solution.
For each reagent listed below indicate if it can be used to
separate the ions. Type "Y" for yes or "N" for no. If the reagent
CAN be used to separate the ions, give the formula of the
precipitate. If it cannot, type "No"
