According to Le Chatelier’s Principle, if a system (chemical reaction) is at equilibrium and we disturb it, then the system will readjust to maintain its equilibrium state.
Le Châtelier's principle states that if a stress is applied to a system at equilibrium, the system will shift to relieve that stress. This is true for all types of equilibrium, including the dissolution of salts that are only sparingly soluble.
Here is the chemical reaction that represents solid silver bromide dissolving in water:
AgBr(s) ⇌ Ag+(aq) + Br−(aq)
Ksp = 5.3 × 10−13
Which of the following actions would shift this reaction toward solid silver bromide?
a) Add more silver bromide.
b) Add more bromide ions.
c) Remove bromide ions.
d) Remove silver ions.
