Arrhenius and Bronsted-Lowry Acid/Base Practice

Front

What is a Bronsted-Lowry acid?

Back

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

Front

What is a Bronsted-Lowry base?

Back

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

Front

How does H2O act as a base according to Bronsted-Lowry theory?

Back

H2O acts as a base when it accepts a proton (H+).

Front

What is an Arrhenius acid?

Back

An Arrhenius acid is a substance that produces H+ ions in aqueous solution.

Front

What is an Arrhenius base?

Back

An Arrhenius base is a substance that produces OH- ions in aqueous solution.

Front

Give an example of a Bronsted-Lowry acid.

Back

Hydrochloric acid (HCl) is a Bronsted-Lowry acid because it donates H+ ions.

Front

Give an example of a Bronsted-Lowry base.

Back

Ammonia (NH3) is a Bronsted-Lowry base because it accepts H+ ions.

Front

What is the main difference between Arrhenius and Bronsted-Lowry definitions of acids and bases?

Back

Arrhenius defines acids as H+ producers and bases as OH- producers, while Bronsted-Lowry defines acids as H+ donors and bases as H+ acceptors.

Front

What happens when a Bronsted-Lowry acid reacts with a Bronsted-Lowry base?

Back

The Bronsted-Lowry acid donates a proton to the Bronsted-Lowry base.

Front

What is the conjugate base of HCl?

Back

The conjugate base of HCl is Cl-.
