Front

What is a Bronsted-Lowry acid?

Back

A Bronsted-Lowry acid is a substance that donates a proton (H+) to another substance.

Front

What is a Bronsted-Lowry base?

Back

A Bronsted-Lowry base is a substance that accepts a proton (H+) from another substance.

Front

Define conjugate acid.

Back

A conjugate acid is the species formed when a Bronsted-Lowry base accepts a proton.

Front

Define conjugate base.

Back

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

Front

What is the relationship between acids and their conjugate bases?

Back

The relationship is that when an acid donates a proton, it becomes its conjugate base.

Front

What is the relationship between bases and their conjugate acids?

Back

When a base accepts a proton, it becomes its conjugate acid.

Front

What is an Arrhenius acid?

Back

An Arrhenius acid is a substance that increases the concentration of H+ ions in aqueous solution.

Front

What is an Arrhenius base?

Back

An Arrhenius base is a substance that increases the concentration of OH- ions in aqueous solution.
