Question

What type of chemical reaction take place when ammonia and hydrogen chloride are mixed?

Answer 1

It is basically an acid- base reaction meaning thereby that acid reacting with a base to from a salt.

Here ammonia is a base (a Lewis base) because it has a lone pair of electrons on the nitrogen atom which can be donated to an acid, here hydrogen chloride.

The proton (H+) of hydrogen chloride (ionized as H+ and Cl-) receives the lone pair of electrons from N atom whereupon N having lost the pair of electrons becomes positively charged and H+ losing positive charge on receiving pair of electrons becomes H sharing the pair of electrons with N atom.

Thus NH3 on receiving the H+ of HCl (H+ and Cl-) forms NH4+ (ammonium ion) which on bonding with Cl- ion (from HCl) gives NH4Cl (ammonium chloride).

The reaction is represented as NH3 +HCl= NH4Cl.

Answer 2

Answer:

the ammonia is breaked down and will produce NH4cl
