Given the following equilibrium in an aqueous solution: (2)
BiCl3 (s) + H2O < === > BiOCl + 2 HCl (strong acid)
What will happen to this equilibrium if you add:
a. H3O+
b. OH-
c. Ag+
d. Water
Homework Answers
a) if H3O+ is added then acidity increases as HCl is acidic and H3O+ is acidic. So reaction will proceed to neutralize this affect. Hence equilibrium shifts towards left side i.e reactants side ( to decrease acidity)
b) OH- reacts with HCl and thus decreases acidity. Reaction will proceed towards side to neutralize this affect i.e to produce more HCl. Hence equilibrium shifts right side
c) Ag+ reacts with HCl to form AgCl. Hence to HCl decreases . Equilibrium shifts right side to produce more HCl
d) Adding H2O increases H2O . Thus equilibrium shifts in right direction ( to decrease H2O)
