Step 1 (pre-class step): Addition of sodium chloride to the silver nitrate solution forms a precipitate of silver chloride.ĪgNO 3(aq) + NaCl(aq) –> AgCl(s) + NaNO 3(aq)ĪgCl(s) Ag +(aq) + Cl -(aq) Ksp =1.8 x 10 -10 Have the students predict what will happen upon addition of the acetic acid. Add the ammonia to dissolve the silver chloride and produce the soluble silver ammonia complex ion.Ģ. ![]() Add 10 mL 0.1 M silver nitrate and 30 mL 1.0 sodium chloride to the beaker to form the precipitate.ġ. Place 200 mL of water in a 600 mL beaker. *Shared item: located in the top drawer of the central bench opposite the chemical storage cabinets.ġ. Ammonia and acetic acid are located in the cabinets under the hood. ‡Solutions are located on the solutions shelves. 2 graduated cylinders (1 50 ml, 1 10 ml).Adding a second clear liquid produces a precipitate again. Subjects: Solubility-K sp, precipitation reactions, complex ions, Le Chatlier’s principleĭescription: A precipitate of silver chloride is dissolved upon addition of a clear liquid. 15.5 Silver Salt Equilibrium and LeChatlier’s Principle (check)
