Answer: The equilibrium will shift in the direction of [tex]NH_3[/tex]
Explanation:
The chemical equation for the aqueous solution of ammonia follows:
[tex]NH_3+H_2O\rightleftharpoons NH_4^++OH^-[/tex]
According to Le-chtelier's principle:
If there is any change in the variables of the reaction, then the equilibrium will shift in that direction of equilibrium to minimize the effect.
If we add more amount of [tex]NH_4^+[/tex] to the solution, more of the products will be present. But according to Le-chtelier's principle, to minimize this effect, the equilibrium will shift in the backward direction that in the direction of [tex]NH_3[/tex]
Hence, the equilibrium will shift in the direction of [tex]NH_3[/tex]
