You are presented with three solutions:
Hg2(NO3)2, Ba(ClO4)2, and CaBr2
The Problem is, the labels have fallen off the containers, so you don't know which is which. You have at your disposal labeled solutions of NaCl, NaOH, Na2SO4, and Na2CO3. Write out ALL the reactions that can occur between the labeled solutions and the unlabeled ones, AND describe how you would use these reactions to put labels on the solutions.
