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...
