Ammonium chloride (NH4Cl(s))is added to an aqueous solution of hypochlorous acid, HOCH(aq). Will a reaction occur?

The aqueous solution of ammonium chloride is acidic.  

Ammonium chloride (NH  

4

​  

Cl) is a salt of a strong acid (HCl) and a weak base (NH  

4

​  

OH). Hence, in an aqueous solution, it shows acidic properties.

When mixed with water, it gets hydrolysed as follows.

NH

​  

Cl+H

​  

OH+HCl

The salt and the strong acid (HCl) get ionised while the weak base (NH  

4

​  

OH) remains unionised.

Explanation:

neutrons are in the middle of the atom and the electrons, which are much smaller.
