Worksheet #5: Double-Replacement Reactions In these reactions, all you do is look at the names of the reactants, and "switch partners". Just be sure that the new pairs come out with the positive ion named first, and paired with a negative ion. 1. aluminum iodide + mercury(II) chloride Æ 2. silver nitrate + potassium phosphate 3. copper(II) bromide 4. calcium acetate 5. ammonium chloride + 6. calcium nitrate hydrochloric acid 7. iron(II) sulfide 8. copper(II) hydroxide 9. calcium hydroxide 10. calcium bromide + + aluminum chloride + + Æ mercury(I) acetate acetic acid Æ Æ hydrochloric acid + Æ sodium carbonate + + Æ Æ Æ phosphoric acid Æ potassium hydroxide Æ Examine the products of the reactions on this page, and determine in each whether a gas, water, or a precipitate is formed. Use solubility Table B.9 on page R54 at the back of your textbook to determine the solubilities of the reaction products. If there is no gas, water, or precipitate produced, put an "X" through the yield sign, because no reaction occurs.
