when naming ionic compounds — those are only used in naming covalent molecular compounds.

Is the following a redox reaction? Explain.<br> NH₃(aq) + HCl(aq) → NH₄Cl(aq)
jeyben [28]

The process is not a redox reaction.

The reaction between ammonia (NH_{3} )and hydrochloric acid (HCl) to produce ammonium chloride (NH_{4} Cl) has modified the oxidation number of no atom in the reactants. As a base, ammonia interacts easily with hydrochloric acid to produce ammonium chloride salt. A neutralization reaction between an acid and a base is what the described process is, and it is NOT a redox reaction.

A reaction is referred to as a redox reaction if two or more reactants belonging to a single reaction exchange one or more electrons, i.e., one reactant releases one or more additional electrons while the other obtains one or additional electrons. The reacted substance that releases electrons is oxidized and becomes a reducing substance. A reduced oxidizing agent is the reactant that accepts electrons.
