Question

Consider the following chemical equation in equilibrium.

H2SO4(aq)   2H+ + SO42–   

What will happen to the chemical equilibrium if HCl is added to the system?
The chemical equilibrium will shift to the right.The chemical equilibrium will be lost permanently.The chemical equilibrium will not be affected.The chemical equilibrium will shift to the left.

Answer 1

Adding HCl will increase the H+ concentration. According to Le Chatelier's Principle the reaction will shift to the left to counteract the increase in H+ ions.

Answer 2

The chemical equilibrium will shift to the left when HCl is added: option D.

What is chemical equilibrium?

Chemical equilibrium refers to a state in closed system, in which the rate of the forward reaction is equal to the rate of the backward reaction.

For the given reaction in chemical equilibrium, addition of HCl will increase the concentration of hydrogen ions in the forward reaction, therefore, equilibrium will shift to the left to annul the change.
