Which danish chemist advanced the concept that an acid is simply a proton donor?
Søren Peder Lauritz Sørensen, a Danish chemist, is known for advancing the concept that an acid is simply a proton donor. He introduced the concept of pH to measure acidity and alkalinity, defining it as the negative logarithm of the hydrogen ion concentration in a solution.
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 definition of acids and bases emphasizes of protons?
The Brønsted-Lowry definition of acids and bases emphasizes the transfer of protons. According to this definition, acids donate protons, while bases accept protons. This concept focuses on the role of protons in acid-base reactions.
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 limitations of Bronsted-Lowry concept?
Limitations of Bronsted lowry concept(i) The protonic definition cannot be used to explain the reactions occuring in non-protonic solvents such as COCl2, SO2, N2O4, etc.(ii) It cannot explain the reactions between acidic oxides like etc and the basic oxides like etc which take place even in the absence of the solvent e.g.,There is no proton transfer in the above example.(iii) Substances like BF3, AlCl3 etc, do not have any hydrogen and hence cannot give a proton but are known to behave as acids.
Is sulphate ion amphoteric?
sulphate ion is not amphoteric because according to Bronsted-Lowry concept an amphoteric specie is that which can donate as well as accept aproton but sulphate ion is not capable of donating proton so it is not amphoteric

What is the Bronsted-Lowry definition of acid?
According to this concept an acid is a compound which donates a proton (H+). for example, HA + H2O ------------> A- + H3O+ acid water base hydronium ion
Why was the Arrhenius theory of acids and bases modified?
The Arrhenius theory was modified because it was limited in its scope to only aqueous solutions and did not account for reactions in non-aqueous solvents. The Bronsted-Lowry theory extended the concept of acids and bases to include proton transfer reactions in all solvents, leading to a more inclusive and versatile understanding.
When ammonia is added to water does it act as an acid or a base?
When ammonia is added to water, it acts as a base. This is because according to Lewis Concept of Acids and Bases, a lone pair donor is a base. NH(3) donates its lone pair to H+ ion from water and hence is a base.
What is true of bronsted-lowery base?
A Brønsted-Lowry base is a substance that can accept a proton (H+ ion) in a chemical reaction. This definition broadens the concept of bases beyond hydroxide ions. Basic solutions typically contain Brønsted-Lowry bases.
Did Johannes bronsted get awards for his theory?
Yes, Johannes Nicolaus Brønsted received awards for his work on the Brønsted-Lowry theory. He was awarded the prestigious Langmuir Prize of the American Chemical Society in 1949 for his contributions to chemical thermodynamics and the concept of proton transfer.
Business entity concept?
According to this concept, business is treated as a unit separate and distinct from its owner.
