Ammonium hydroxide ionizes as follows: nh4oh(s) nh4 +(aq) + oh-(aq). if an excess of ammonium salt, such as nh4cl (which ionizes to give nh4 +(aq) ions) is added to the equilibrium shown above, you could predict that the result will be

The dissociation of the base will be further suppressed.

Explanation: Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.

This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

For the given equation:

If an excess of ammonium salt, such as (which ionizes to give (aq) ions)

If the concentration of that is the product is increased, so according to the Le-Chatelier's principle, the equilibrium will shift in the direction where decrease of concentration of takes place. Therefore, the equilibrium will shift in the backward direction and the ions will start associating to form .
