Acids, Bases, Conjugate Acids, and Conjugate Bases

Front

What is an acid according to Arrhenius?

Back

A substance that contains hydrogen and ionizes to produce H+.

Front

What is a base according to Bronsted-Lowry?

Back

A substance that accepts a hydrogen (H+) ion.

Front

What is a conjugate acid?

Back

The species formed when a base gains a hydrogen ion.

Front

What is a conjugate base?

Back

The species formed when an acid donates a hydrogen ion.

Front

What is the role of H+ ions in acid-base reactions?

Back

H+ ions are donated by acids and accepted by bases.

Front

What is the difference between strong and weak acids?

Back

Strong acids completely ionize in solution, while weak acids partially ionize.

Front

What is the pH scale?

Back

A scale used to measure the acidity or basicity of a solution, ranging from 0 (acidic) to 14 (basic).

Front

What is a neutralization reaction?

Back

A reaction between an acid and a base that produces water and a salt.

Front

What is the significance of conjugate acid-base pairs?

Back

They help to understand the transfer of protons in acid-base reactions.

Front

What is the definition of a strong base?

Back

A base that completely dissociates in solution to produce OH- ions.
