How are conjugate acid-base pairs identified in an aqueous ionization reaction?
Identify the reactant acid and the product it becomes after losing a proton (conjugate base), and the reactant base and the product it becomes after gaining a proton (conjugate acid).
What is a conjugate acid-base pair?
A conjugate acid-base pair consists of two species that differ from each other by the presence or absence of a single proton.
In a reaction involving proton transfer, how do you identify the Brønsted-Lowry acid?
The Brønsted-Lowry acid is the species that loses a proton during the reaction.
What is the definition of a Brønsted-Lowry acid?
A Brønsted-Lowry acid is defined as a proton (H+) donor.
What occurs when an acid or base ionizes in water?
When an acid or base ionizes in water, proton transfer occurs, creating conjugate acid-base pairs whose relative strengths can be compared.
What is the definition of a Brønsted-Lowry base?
A Brønsted-Lowry base is defined as a proton (H+) acceptor.
What is the fundamental process in a Brønsted-Lowry acid-base reaction?
The fundamental process in a Brønsted-Lowry acid-base reaction is the transfer of a proton from an acid to a base.
When a Brønsted-Lowry base accepts a proton, what does it become?
When a Brønsted-Lowry base accepts a proton, it becomes its conjugate acid.
What special role can water play in aqueous acid-base reactions?
In aqueous solutions, water's molecular structure allows it to act as both a proton acceptor (a base) and a proton donor (an acid).
When a Brønsted-Lowry acid donates a proton, what does it become?
When a Brønsted-Lowry acid donates a proton, it becomes its conjugate base.
