Question

1. Write a list of all the compounds which are soluble in water. Include also all the compounds appearing at the top and side of the table. Base this list only on the data from this experiment. (This is an exercise in deductive reasoning. Hint: Look at the mixtures in which no precipitate formed. What does the experiment tell you about those possible products? If you can't figure out how to do this, ask your instructor for another hint.) Include also, all the compounds appearing at the top and side of the table.

Using the list from question above, figure out the identity of the precipitates in each of the reactions that formed one, and make a list of them. (This is another exercise in deductive reasoning. Hint: in each case where a precipitate forms, the other product is soluble. Again, if you can't figure out how to do this, ask your instructor for further hints).
