Question

Five unlabeled bottles containing the solutions below in some scrambled sequence will be identified.

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 on the NIE line. All equations must be balances, contain the appropriate ion charges and phases. 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)

1. sulfuric acid and sodium carbonate
