Many of the reactions utilized in this laboratory experiment involve substances with small solubility product constants. AgCl is one such substance. Nevertheless, a precipitate of AgCl will dissolve in either 6 M HCl or 6 M NH3.

(a). Briefly explain why each of these reagents dissolves AgCl(s). Write appropriate equations to support your answer.

(b). Briefly explain why it is possible to reprecipitate AgCl (s) by adding HCl to [Ag(NH3)2]+ ion but not by adding ammonia to [AgCl2]- ion. Write appropriate equations to support your answer.

I have provided the information for the lab below. I want to see the chemical reactions that take place during each step of the experiment. So in the procedures when a chemical was added i would like to see what the products and byproducts that were formed. I also want to see one over all reaction for this experiment to just get an overview of what exactly is happening during the experiment. Thank you:) Part B: Synthesis of [Co(NH3)5Cl]Cl2 Objective:...

Chemical Reactions Types and Their Equations Making Heat with Chemical Reactions Have you ever wondered how an instant heat pack works? A disposable heat pack works by a chemical reaction that combines iron in the package with oxygen from the air when the outer packaging is removed producing iron oxide. You have probably seen the product of this reaction in what is commonly called rust. The reaction releases heat, which allows the pack to reach a sufficient temperature that is...
