Johannes Nicolaus Brønsted and Thomas Martin Lowry, independently, formulated the idea that acids donate protons (H +) while bases accept protons.

In short, a Brønsted-Lowry acid is a proton donor (PD), while a Brønsted-Lowry base is a proton acceptor (PA). According to this theory, ammonia (NH 3) is a base even though it does not contain …

Using the Brønsted-Lowry definition, an acid-base reaction is any reaction in which a proton is transferred from an acid to a base. We can use the Brønsted-Lowry definitions to discuss acid-base …

Nov 30, 2025 · A somewhat more general acid-base theory, the Brønsted-Lowry theory, named after Danish chemist Johannes Nicolaus Brønsted and English chemist Thomas Martin Lowry, defines an …

The Brønsted-Lowry theory of acids and bases, developed by Johannes Nicolaus Brønsted and Thomas Martin Lowry in 1923, offers a fundamental perspective on acid-base behavior.

Jul 23, 2025 · In the Bronsted-Lowry theory, acids and bases are defined based on proton transfer. Acids donate protons while bases accept them. This concept expands the definition of acids and …

A compound that donates a proton to another compound is called a Brønsted-Lowry acid, and a compound that accepts a proton is called a Brønsted-Lowry base. An acid-base reaction is the …

Feb 22, 2022 · According to the Bronsted Lowry theory, an acid is a proton donor. Since a proton is essentially the H + ion, all Bronsted-Lowry acids contain hydrogen. A base is a proton acceptor. …

Note: Current UK A' level syllabuses concentrate on the Bronsted-Lowry theory, but you should also be aware of Lewis acids and bases. The Arrhenius theory is of historical interest only, and you are …

6 days ago · A Brønsted-Lowry acid is a molecule or ion that donates a hydrogen ion in a reaction. A Brønsted-Lowry base is a molecule or ion that accepts a hydrogen ion in a reaction.
