You are given an unknown (solid or solution) and told that it can be one of the other of the compounds in the pairs listed below. Describe a simple chemical test (Not a flame test) using only reagents from our chemistry kits that would enable you to distinguish between the two possiblities. Describe what you would expect for each and write balanced, net iontic equations for any reaction that occur. Note that this question reviews all of the Qualitative Analysis experiments we have done.
A. AgCl (s) and BaSO4(s)
B. Fe^2+(aq) and Sr^2+(aq)
C. Hg2^2+(aq) and Mn^2+(aq)
D. CoS(s) and BaCO3(s)
