Question

For the reaction ag2s(s) ⇌ 2ag (aq) + s2−(aq). What happens to the equilibrium position if the amount of silver ion is halved?

Answer 1

The equilibrium shifts to the right.

What is Equilibrium law?

• According to this law, if a process in equilibrium is subjected to change in the factors that affect equilibrium, then the equilibrium shifts in a specific direction which tends to counteract the effect of change imposed.

• The common ion effect is a result of this law

• Factors affecting equilibrium are

1. Change in concentration of reactants or product
2. Change in temperature
3. Change in pressure
4. Adding an inert gas

According to this law,

The concentration of the product is decreased and hence, the equilibrium shifts to the right.
