The Brønsted-Lowry concept defines an acid as a proton donor and a base as a proton acceptor, which allows for a broader range of substances to be classified as acids and bases compared to the Arrhenius definition. This concept also explains acid-base reactions involving solvent molecules as proton donors or acceptors without requiring water as the solvent, making it versatile and widely applicable in different chemical systems. Furthermore, the Brønsted-Lowry concept accounts for the transfer of protons in reactions, providing a fundamental understanding of how acids and bases interact.
The Bronsted-Lowry concept can be applied to non-aqueous mediums since it focuses on the transfer of protons between acid-base pairs. Whether in water or another solvent, a substance can still act as an acid by donating a proton (H+) and a base by accepting a proton. This fundamental transfer of protons can occur in various solvents beyond water, allowing the concept to be applicable in non-aqueous mediums.
The concept of conjugate acid-base pairs was proposed by G. N. Lewis in 1923. Later, this concept was further developed by G. S. Hammond in 1955, who introduced the idea of considering the relative stability of the conjugate acid-base pairs.
No, according to the Brønsted-Lowry concept, an amphoteric substance can act as both an acid and a base. Ammonia (NH3) is a weak base, as it can accept a proton (H+) to form its conjugate acid NH4+. It does not have the ability to donate a proton, so it is not considered amphoteric according to the Brønsted-Lowry concept.
NaOH is a base. It is a strong base known as sodium hydroxide.
The Brønsted-Lowry definition defines an acid as a substance that donates a proton (hydrogen ion). In this definition, an acid is a proton donor, while a base is a proton acceptor.

A neutralization reaction is a reaction between a base and an acid; the products are a salt and water.

The conjugate acid of HCO3- is H2CO3 (carbonic acid). When HCO3- accepts a proton (H+), it forms H2CO3. This reaction illustrates the Bronsted-Lowry concept of conjugate acids and bases, where the base (HCO3-) accepts a proton to become its conjugate acid (H2CO3).
Acid + base conjugate base + conjugate acid
Acid + base salt + water
Yes, a Brønsted-Lowry acid can be a different concept from an Arrhenius acid. While both concepts define acids based on their ability to donate protons, the Arrhenius definition is limited to substances that produce H+ ions in aqueous solutions, whereas the Brønsted-Lowry definition extends to reactions that occur in non-aqueous solvents.
Acids are substances that will donate a proton, while bases are substances that will accept a proton.
Acetamide is a weak base. It can undergo protonation to form the conjugate acid, acetic acid, in acidic solutions.
