4. When CoCl2 is dissolved in water, the resulting solution is pink because of the presence of only) octahedrally coordinated [CoCI(H20)s] coordination complexes. If concentrated hydrochloric acid (a source of Cl) is added to this solution, the following equilibrium is established. [CoCI(H20)s] (aq)+ Cl (aq) [CoCl2(H20)2](aq) + 3H20(1) AH >0 Where [CoCl2(H20)2] is also soluble in water. a) Write a Keq expression for this equilibrium b) Suppose we systematically add increasing amounts of Cr to this system, while maintaining a...

Question 3 3 pts In Reaction 2, you added silver nitrate (AgNO3) to your solution of 1.0 M CoCl2. As mentioned in the lab procedure, silver nitrate dissociates in solution, yielding Agt and NO3. Silver I (Agt) loves chloride ions and will strongly bind to any that it can find. Upon binding with the chloride ions, a precipitate forms. Using your lab data to help you, answer the following questions below. + 4 CI...

Part I Color changes of Methyl Violet. We will study the following reaction: HMV (aq) + MV (aq) + H* (aq) yellow greenish-blue violet Step 1. Place about 4 mL of distilled water in a regular test tube. Add two drops of methyl violet indicator. Record the color of the solution. Violet Next, add drop by drop, add 6M HCI. This forces equilibrium to be shifted to the left or right-circle the right answer). Adding HCl changes color from to...
