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.

How can you justify that bronsted lowry concept of acid and bases are applicble to non aqeous medium?
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.
What scientists came up with the concept of conjugate acid-base pairs?
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.
Is ammonia amphoteric according to bronsted lawry concept?
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.
Is NaOH a acid base or salt?
NaOH is a base. It is a strong base known as sodium hydroxide.
What is the Bronsted-Lowry definition of acid?
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.

What do you mean by neutralization reaction according to Arrhenius acid base concept?
A neutralization reaction is a reaction between a base and an acid; the products are a salt and water.

What is the conjugate acid of HCO3- and why?
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).
What best describes a bronsted lowry acid base reaction?
Acid + base conjugate base + conjugate acid
Could a bronsted-lowry acid not be an arrhenius acid?
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.
What is Arrhenius acid base concept?
Acids are substances that will donate a proton, while bases are substances that will accept a proton.
What are the Categories of Arrhenius acid and Arrhenius base?
What is Arrhenius concept of acid and base?The universal aqueous acid-base definition of the Arrhenius concept is described as the formation of water from hydrogen and hydroxide ions, or hydrogen ions and hydroxide ions from the dissociation of an acid and base in aqueous solution:H+ (aq) + OH− (aq) H2O(In modern times, the use of H+ is regarded as a shorthand for H3O+, since it is now known that the bare proton H+ does not exist as a free species in solution.)This leads to the definition that in Arrhenius acid-base reactions, a salt and water is formed from the reaction between an acid and a base. In other words, this is a neutralization reaction.acid+ + base− → salt + water
Is acetamide acid or base?
Acetamide is a weak base. It can undergo protonation to form the conjugate acid, acetic acid, in acidic solutions.
