Balance NH3 + HCl = NH4Cl (Ammonia and Hydrochloric Acid)Click to see full answer. Similarly, it is asked, what is the reaction between ammonia and hydrochloric acid?The reaction equation between ammonia (NH3) and hydrochloric acid (HCl) is written as follows: NH3+HCl=NH4Cl. Ammonia is a weak base that reacts with hydrochloric acid, forming a compound called ammonium chloride.Furthermore, what is the chemical reaction for ammonia? Chemical reactivity of ammonia Ammonia readily dissolves in water with the liberation of heat. NH3 + H2O ⇌ NH4+ + OH− These aqueous solutions of ammonia are basic and are sometimes called solutions of ammonium hydroxide (NH4OH). One may also ask, what is the chemical reaction of hydrochloric acid? Magnesium reacts with hydrochloric acid according to the equation: Mg(s) + 2 HCl(aq) –> MgCl 2(aq) + H 2(g) This demonstration can be used to illustrate the characteristic reaction of metals with acid, a single replacement reaction, or to demonstrate the generation of hydrogen gas.What is the reaction of ammonia with an acid?Ammonia reacts with acids to produce ammonium ions. The ammonia molecule picks up a hydrogen ion from the acid and attaches it to the lone pair on the nitrogen. If the reaction is in solution in water (using a dilute acid), the ammonia takes a hydrogen ion (a proton) from a hydroxonium ion.
