Flashcard - Honors Conjugates acids and Bases

Front

What is a Brønsted-Lowry acid?

Back

A Brønsted-Lowry acid is a substance that donates a proton (H+) in a chemical reaction.

Front

What is a Brønsted-Lowry base?

Back

A Brønsted-Lowry base is a substance that accepts a proton (H+) in a chemical reaction.

Front

What is a conjugate acid?

Back

A conjugate acid is the species formed when a Brønsted-Lowry base gains a proton.

Front

What is a conjugate base?

Back

A conjugate base is the species formed when a Brønsted-Lowry acid donates a proton.

Front

Identify the conjugate base of HCl.

Back

The conjugate base of HCl is Cl⁻.

Front

Identify the conjugate acid of NH₃.

Back

The conjugate acid of NH₃ is NH₄⁺.

Front

What is the role of water in acid-base reactions?

Back

Water can act as both an acid and a base, depending on the reaction.

Front

What is the significance of the H⁺ ion in acid-base chemistry?

Back

The H⁺ ion (proton) is central to the definition of acids and bases in the Brønsted-Lowry theory.
