Precipitation Reactions Pages 153-158

When two ionic solutions are mixed, an insoluble substance may form. The solid separates from the solution and is known as a precipitate. Determining if a reaction will form a precipitate requires memorization of some basic solubility rules.

Solubility Rules – AP Chemistry All sodium, potassium, ammonium, and nitrate salts are soluble in water. Memorization of other “solubility rules” on page 156 is beyond the scope of this course and the AP Exam.

Double Replacement Reactions The ions of two compounds exchange places in an aqueous solution to form two new compounds. AX + BY → AY + BX One of the compounds formed is usually a precipitate (an insoluble solid), an insoluble gas that bubbles out of solution, or a molecular compound, usually water.

Double replacement forming a precipitate… Lead(II) nitrate + potassium iodide → lead(II) iodide + potassium nitrate Double replacement (ionic) equation Pb(NO3)2(aq) + 2KI(aq) → PbI2(s) + 2KNO3(aq) Complete ionic equation shows compounds as aqueous ions Pb2+(aq) + 2 NO3-(aq) + 2 K+(aq) +2 I-(aq) → PbI2(s) + 2K+(aq) + 2 NO3-(aq) Net ionic equation eliminates the spectator ions Pb2+(aq) + 2 I-(aq) → PbI2(s)
