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 Ag+ and NO3-. Silver I (Ag+) 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. Co(H2O)6^2+ (aq) + 4 Cl- <---> CoCl4^2- (aq) + 6H20(I) (Pink) (blue) Immediately following the addition of AgNO3 to your reaction:
Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
Bronsted Lowry Base In Inorganic Chemistry
Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.

(Pink) (blue)
Immediately following the addition of AgNO3 to your reaction:
- The value of Kc will be (less than/more than/equal) Qc.
- Equilibrium will shift to (Favor reactant/favor prodcut) .
- After AgNO3 is added, the color of the cobalt solution will be ( more pink/more blue/same color)
