Final answer:

The reaction NH3 + HCl → NH4Cl is an acid-base reaction where ammonia reacts with hydrochloric acid to form the salt ammonium chloride, resulting in a slightly acidic solution when dissolved in water.

Step-by-step explanation:

The chemical reaction NH3 + HCl → NH4Cl is an example of an acid-base reaction. Ammonia (NH3) reacts with hydrochloric acid (HCl) to form ammonium chloride (NH4Cl). When dissolved in water, NH3 partially reacts to form NH4+ and OH- ions, though only about 1% of the ammonia exists as NH4+ under typical conditions. This reaction can be described as NH3(aq) + H2O(l) → NH4+(aq) + OH-(aq). Ammonium chloride, the product of this reaction, is a salt created by neutralizing a strong acid (HCl) with a weak base (NH3). It is soluble in water, and the chloride ion (Cl-) does not hydrolyze significantly because it is the conjugate base of the strong acid HCl. However, the ammonium ion (NH4+) can donate a proton to water, acting as an acid, leading to a slightly acidic solution. The degree of acidity can be determined using the equilibrium constant (Ka).

Answer:

A combination reaction

Step-by-step explanation:

The chemical reaction between ammonia and hydrochloric acid as shown below:

NH₃ + HCl → NH₄Cl

is a combination reaction.

In a combination reaction, two compounds combines together to give one compound.

A combination reaction is also known as a synthesis reaction.

A single product forms from tow or more reactants.

The driving force for such reaction is the large and negative heat of formation of the product.
