Name __________________________________________ Period ________ Date _________________ Double-Replacement Reactions Worksheet 1 Remember, cations are exchanged between compounds. A+B- + C+D-  A+D- + C+BComplete the word equation. Write and balance the chemical equation. It may be easier to write the chemical equation before completing the word equation. For each reaction, include the correct state that each compound is in. For all reactants, this should be aqueous. Use your solubility chart to determine the solubility of the reaction products of ionic compounds. Specify with “(ppt)” if an insoluble product results. Use “(g)” if a gas is produced. If both products are soluble, draw an “X” over the arrow to indicate that no reaction occurs. In both situations with mercury, the mercury product will form a precipitate. 1. aluminum iodide + 2. silver nitrate potassium phosphate + mercury(II) chloride 3. copper(II) bromide + aluminum chloride 4. calcium acetate + sodium carbonate 5. ammonium chloride + mercury(I) acetate 6. calcium nitrate + hydrochloric acid 7. iron(II) sulfide + hydrochloric acid 8. copper(II) hydroxide + 9. calcium hydroxide + 10. calcium bromide + acetic acid phosphoric acid potassium hydroxide (gas) (water) (water)
