On this assumption, the range of acids includes such varied materials as bisulfate ion, HSO4−; acetic acid, CH3COOH; water, H2O; hydronium ion, H3O+; and ammonium ion, NH4+.

Encyclopedia Britannica

The macronutrient source of the macroelement nitrogen, for example, is the nitrate ion (NO3−); alternatively, nitrogen is taken up as the ammonium ion (NH4+) or as amino acids.

Encyclopedia Britannica

The total tubular cell secretion of hydrogen ion is therefore the sum of titratable acidity, the amount of ammonium ion excreted, and the amount of bicarbonate ion reabsorbed.

Encyclopedia Britannica

Further, the ammonium ion was ascertained in the efflorescence samples.

Heritage Science

Expert writing Tips

Best practice

When writing scientific reports, specify the concentration of "ammonium ion" using appropriate units (e.g., mg/L, ppm) to ensure clarity and reproducibility.

Common error

Avoid using "ammonia" and "ammonium ion" interchangeably. Ammonia (NH3) is a neutral molecule, while "ammonium ion" (NH4+) is a positively charged ion formed when ammonia accepts a proton. Use the correct term based on the chemical context.

Linguistic Context

The primary grammatical function of "ammonium ion" is as a noun phrase, typically serving as the subject or object in a sentence. It identifies a specific chemical species. Ludwig AI confirms its proper usage in scientific literature.

Ludwig's WRAP-UP

The phrase "ammonium ion" is a grammatically correct noun phrase predominantly used in scientific and technical contexts to refer to the NH4+ cation. Ludwig AI confirms its proper and frequent usage within academic, scientific, and encyclopedic resources. While it is a common term in its specific domain, it's crucial to differentiate it from ammonia (NH3). Related terms include "ammonium cation" and "protonated ammonia". When writing, ensure the proper units of concentration are specified and that it isn't confused with un-ionized ammonia. As per Ludwig's analysis, the expression appears overwhelmingly in scientific publications, suggesting that it should be used in formal settings only.

FAQs

How is "ammonium ion" formed?

The "ammonium ion" (NH4+) is formed when ammonia (NH3) accepts a proton (H+). This typically occurs when ammonia is dissolved in water, resulting in the protonation of ammonia.

What is the difference between "ammonium ion" and "ammonia"?

"Ammonium ion" (NH4+) is a positively charged ion, while "ammonia" (NH3) is a neutral molecule. "Ammonium ion" is formed when ammonia accepts a proton.

In what contexts is "ammonium ion" commonly found?

"Ammonium ion" is commonly found in biological systems, soil, wastewater, and various chemical reactions. It plays a crucial role in nitrogen cycling and is essential for plant growth. It is also used in various industrial processes.

What are some synonyms for "ammonium ion"?

While there aren't direct synonyms, related terms include "ammonium cation" and the chemical formula "NH4+". Contextually, phrases like "protonated ammonia" may also be relevant.
