Bronsted and Lowry developed their definition in 1923. According to Bronsted-Lowry, what is an acid?
A Bronsted-Lowry acid is a proton (H+) donor. What does the term 'proton' refer to in Bronsted-Lowry theory?
In Bronsted-Lowry theory, 'proton' refers to H+. How does the Bronsted-Lowry definition of acid relate to the Arrhenius definition?
Both definitions agree that acids have H+ and increase H+ concentration in solution. What is the Bronsted-Lowry definition of a base?
A Bronsted-Lowry base is a proton (H+) acceptor. How does the Bronsted-Lowry definition of a base differ from the Arrhenius definition?
Bronsted-Lowry bases accept H+, while Arrhenius bases must produce OH-. Why can Bronsted-Lowry bases accept H+?
They can accept H+ because they have lone pairs or a negative charge. What is a conjugate acid-base pair?
A conjugate acid-base pair consists of two species that differ by only one hydrogen atom. Give an example of a conjugate acid-base pair involving water.
H2O and OH- are a conjugate acid-base pair, differing by one H+. How do H3O+ and H2O relate as conjugate acid-base pairs?
H3O+ and H2O are conjugate acid-base pairs, differing by one H+. Can Bronsted-Lowry acids and bases exist in non-aqueous solutions?
Yes, Bronsted-Lowry acids and bases can exist in solutions not made up of water. What is the main requirement for a Bronsted-Lowry acid?
It must be able to donate an H+ (proton). What is the main requirement for a Bronsted-Lowry base?
It must be able to accept an H+ (proton). How do Arrhenius acids compare to Bronsted-Lowry acids?
All Arrhenius acids are also Bronsted-Lowry acids. What is the key difference between conjugate acid-base pairs?
They differ by only one hydrogen atom (H+).
