question : 

For reaction 5, Step 18, explain why the equilibrium shifted to the left.

REACTION 5 16. Place 10 drops of 0.1 M silver nitrate and 1 drop of 1 M ammonia in a small test tube, and add 10 drops of 0.1 M sodium chloride. This should establish the following equilibrium showing the showing the white solid: AgCl (s) + 2NH3 (aq) → Ag(NH3)₂ (aq) + Cl (aq) white solid 17. Using one of the reagents: 0.1 M AgNO3, 0.1 M NaCl, 1 M NH3 force the equilibrium to shift to the right. Record in your Data Table the reagent used, as well as your observations verifying that the equilibrium shifted to the right. 18. Using one of the reagents: 0.1 M NaCl, 1 M NH3 force the equilibrium to shift to the left. Record in your Data Table the reagent used, as well as your observations verifying that the equilibrium shifted to the left. 19. Prepare a new equilibrium solution in a different test tube with 10 drops of 0.1 M silver nitrate, 10 drops of 0.1 M sodium chloride, and enough drops of 1 M ammonia until the precipitate completely dissolves. 20. Add drops of 0.1 M silver nitrate to force the equilibrium to the left. Record in your Data Table your observations verifying that the equilibrium shifted to the left.

Expert Solution
Step 1

on addition of NaCl, concentration of Cl- increases and to minimize the effect of change that is to decrease the concentration of Cl- in product side, equilibrium shifted towards left direction.
