Question

You are given two unlabeled bottles, each of which contains a clear colorless liquid. One of the bottles contains deionized water; one contains a sodium chloride solution. How could you use the method and reagents of this experiment to identify the contents of the two bottles? Describe what you would plan to do and what you would expect to observe. You are given three bottles containing aqueous solutions, labeled A. B. and C. One bottle contains H2SO4, one contains MgCl2, and one contains Na2CO3. When a few' drops from bottle A are mixed with a few drops from bottle B, a white precipitate forms. When B is mixed with C, no change occur. When A is. mixed w ith C, bubbling occurs. Write balanced total ionic and net ionic chemical equations for the reaction of sulfuric acid with magnesium chloride. total ionic net ionic Write balance total ionic and net ionic chemical equation for the reaction of sulfuric acid with sodium carbonate. total ionic net ionic Write balance total ionic and net ionic chemical equation for the reaction of magnesium chloride with sodium carbonate. total ionic net ionic Which bottle contains sulfuric acid? Explain your reasoning. Write molecular, total ionic and net ionic equations for the reaction of barium nitrate with sodium carbonate. molecular: total ionic net ionic

Explanation / Answer

The complete ionic equation is:

Ba+2(aq) + 2 NO3-1(aq) + 2 Na+1(aq) + CO3-2(aq) ==> 2 Na+1(aq) + 2 NO3-1(aq) + BaCO3 (s)

The net ionic equation is:

Ba+2(aq) + CO3-2(aq) ==> BaCO3 (s)

Balanced chemical equation: Ba(NO3)2(aq) + Na2CO3(aq) --> BaCO3(s) + 2Na(NO3)(aq)
