Question

Is ammonium chloride a irreversible reaction?

Answer 1

Reversible and Irreversible Reactions. ... Ammonia is a base, hydrogen chloride is an acid and they react together to form ammonium chloride. NH4Cl ⇌ NH3 + HCl. When you see a reaction written down using a double arrow between the reactants and products, it means that it is reversible.

However, in other reactions, the reverse reaction can happen: the products can react to form the original reactants again. These are called reversible reactions. An example of a reversible reaction involves ammonia gas (NH3), hydrogen chloride gas (HCl), and ammonium chloride solid (NH4Cl).
