- Imagine the following scenario: a student doing the experiment added 20 mL of silver nitrate, AgNO3, to the blue equilibrium mixture. The reaction mixture become pink and cloudy with white precipitate of silver chloride , AgCl, appearing in the bottom of the flask. Can you explain how those observations are consistent with Le Chatelier's principle?
- Imagine the scenario: A student placed pink equilibrium mixture in the hot water. Reaction mixture changed color to blue. Is the reaction endothermic or exothermic? How the change of the temperature influences the equilibrium of this reaction? Explain.

For each experiment described below 1) provide the relevant equilibrium reaction or reactions, 2) use LeChatelier's Principle to explain why the reaction has shifted left (L) or right (R), and 3) answer any other questions. a) To a solution containing 1M Pb(NO3)2, 1 M HCl is slowly added until a white precipitate forms. The mixture is then heated and the precipitate disappears. Is the dissociation of the precipitate endothermic or exothermic? Does the equilibrium constant (Ksp) change when the solution...
