Johannes Nicolaus Brønsted (Danish: [joˈhænˀəs ne̝koˈlɛːus ˈpʁɶnsteð]; 22 February 1879 – 17 December 1947) was a Danish physical chemist who is best known for developing the Brønsted–Lowry acid–base theory; he developed the theory at the same time as (but independently of) Martin Lowry. [1] Brønsted was born in Varde, Denmark on 22 February 1879.

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

Feb 18, 2025 · Johannes Nicolaus Brønsted (born Feb. 22, 1879, Varde, Den.—died Dec. 17, 1947, Copenhagen) was a Danish physical chemist known for a widely applicable acid-base concept identical to that of Thomas Martin Lowry of England. Though both men introduced their definitions simultaneously (1923), they did so independently of each other.

Apr 28, 2021 · Identify a Brønsted-Lowry acid and a Brønsted-Lowry base. Identify conjugate acid-base pairs in an acid-base reaction. The Arrhenius definition of acid and base is limited to substances that can generate H + and the OH − ions in aqueous solutions.

Sep 28, 2021 · Arrhenius acids and bases are a sub-class of Brønsted acids and bases, which are themselves a subclass of Lewis acids and bases. The Arrhenius theory, which is the simplest and least general description of acids and bases, includes acids such as HClO 4 and bases such as NaOH or Mg (OH) 2.

Feb 22, 2022 · The Bronsted Lowry acid and base theory states that an acid donates a proton (hydrogen ion, H+), while a base accepts a proton. The reaction forms the conjugate base of the acid and the conjugate acid of the base. Other names for the theory are the Brønsted–Lowry theory or proton theory of acids and bases.

Brønsted-Lowry theory, a theory, introduced independently in 1923 by the Danish chemist Johannes Nicolaus Brønsted and the English chemist Thomas Martin Lowry, stating that any compound that can transfer a proton to any other compound is an acid, and the compound that accepts the proton is a base.

What Is Bronsted–Lowry Theory? The Bronsted-Lowry theory (Proton theory of acid and base) is an acid-base reaction theory, introduced by Johannes Nicolaus Bronsted (Danish Chemist) and Thomas Martin Lowry (English Chemist) in 1923.

In 1923, chemists Johannes Nicolaus Brønsted and Thomas Martin Lowry independently developed definitions of acids and bases based on the compounds' abilities to either donate or accept protons (H+ H + ions). In this theory, acids are defined as proton donors; whereas bases are defined as proton acceptors.

酸碱质子理论，又稱 布仑斯惕-洛瑞碱酸理论，也稱 布-洛酸鹼學說 （英語： Brønsted–Lowry acid–base theory），是 丹麦 化学家 约翰内斯·尼古劳斯·布仑斯惕 和 英国 化学家 托马斯·马丁·劳里 于1923年各自独立提出的一种 酸碱理论 [1][2]。 该理论认为：凡是可以释放 質子 （氫離子，H +）的 分子 或 离子 为酸（布仑斯惕酸，B酸），凡是能接受氫離子的分子或离子則为碱（布仑斯惕碱，B碱）。 當一個分子或離子釋放氫離子，同時一定有另一個分子或離子接受氫離子，因此 …
