For individual solutions of the cations Ag*, Ba*, Mg*, and Cu*, the following experimental observations were collected:
*Example: When an aqueous solution of hydrochloric acid is added to a solution containing Ag*, a white precipitate (ppt) forms.
From these experimental observations,
a. identify a reagent that distinguishes the chemical properties of Ag and Mg?+. What is the distinguishing
b. identify a reagent that distinguishes the chemical properties of HCl and H,SO,. What is the distinguishing
c. identify a reagent that distinguishes the chemical properties of Ba'* and Cu?+. What is the distinguishing observa-
tion?
*d. identify a reagent that distinguishes the chemical properties of Cu'* and Mg2+
vation?
