WHAT CAUSES THE SILVER CHLORIDE TO DISSOLVE AND NAME THE REAGENT? WHAT EVENTUALLY CAUSES THE SILVER CHLORIDE TO REPRECIPITATE, WHAT IS THE NAME OF THIS REAGENT?
Didn't I suggest to you yesterday that typing in all caps made your post hard to read. A word to the wise should be sufficient.
It's a redox reaction and I believe the reagent is NH3.
b) AgCl dissolves in excess NH3. AgCl is repptd by neutralizing the NH3 with dilute HNO3.
