Problem: CoCl42-(aq, blue) + 6H2O(l) ⇌ Co(H2O)62-(aq, pink) + 4Cl-(aq) [REVERSIBLE EQ.]QUESTION: When the pink equilibrium solution formed from CoCl2 was placed in a hot water bath, the solution turned blue. When placed into an ice bath, it turned back to pink. Cite specific observation results to identify the forward reaction in this equilibrium as an exothermic, or as an endothermic process. Write an equation for this equilibrium depicting heat as a reactant or producr of the reaction.

FREE Expert Solution
  • According to Le Chatelier’s Principle if a system (chemical reaction) is at equilibrium and we disturb it then the system will readjust to maintain its equilibrium state
  • For this reaction, the pink solution containing Co(H2O)62- is produced upon dissolving of CoCl2
