ammonia

[U] Không đếm được

This term carries a strong sensory association with a sharp, stinging odor that triggers an immediate physical reaction in the nostrils. It is most frequently encountered in two distinct spheres: the domestic environment as a harsh cleaning agent and the industrial environment as a chemical precursor. In a medical or biological context, the presence of ammonia often signals a breakdown of proteins or a failure in kidney function, giving the word a clinical connotation of toxicity or metabolic distress when used in a healthcare setting.

Used exclusively as a mass noun to describe the chemical substance regardless of the quantity.
