Five unlabeled bottles containing the solutions below in some scrambled sequence will be provided.
1.5 M H2SO4 1 M Na2CO3
0.1 M SrCl2 3 M NaOH
0.1 M Mg(NO3)2
For the 10 possible mixtures of the five solutions, write the molecular (ME), total ionic (TIE) and net ionic (NIE) equations. When no reaction is expected, write NAR for no apparent reaction. Based on these equations, fill in the prediction matrix. What should go in the prediction matrix is what you would observe (precipitation if a solid product is formed, bubbles if a gas product is formed, heat if water is formed)

Experiment 8 Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of each reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms a product with chloride. Note that the formula of each product is determined by the charges of the ions,...
