Equilibrium: Co(H2O)6 2+ (aq) + 4 Cl-(aq) ⇌ CoCl4 2- (aq) + 6 H2O (l) pink blue a. You put 5 mL of stock solution into each of five test tubes. (25 mLs divided evenly into 5 test tubes). Test tube 1 was your control. To test tube 2, you added some water. Which direction did the equilibrium shift? How do you know? b. To test tube 3 you added some silver nitrate. Did this shift the equilibrium? If so, how is that possible as silver ion and nitrate ion are not in the equation? c. To test tube 5, you put the stock solution into hot water and it turned blue; then you put it into ice water and it turned pink. Explain what happened.
