Arrhenius vs Bronsted Lowry

According to Bronsted-Lowry, what is the definition of an BASE?

• a substance that donates a hydrogen (H+) ion

• a substance that donates a hydroxide (OH-) ion

• a substance that accepts a hydrogen (H+) ion

• a substance that accepts a hydroxide (OH-) ion

What is being donated/accepted between conjugate acid-base pairs?

• a hydrogen (H+) ion

• a hydroxide (OH-) ion

• water

• a neutron

An arrhenius base

• produces hydroxide ions in a solution

• is a proton donor

• produces hydrogen ions in a solution

• is a proton acceptor

A bronsted lowry acid

• produces hydroxide ions in a solution

• is a proton donor

• produces hydrogen ions in a solution

• is a proton acceptor

Water can act as both an acid and a base according to the bronsted lowry model. This means water is

• neutral

• conjugate

• ionic

• amphoteric

Identify the true statement about the following reaction: F^- + H₂O --> HF +OH^-

• H₂O is a bronsted lowry base

• H₂O is not an acid or base according to either model

• H₂O is a bronsted lowry acid

• H₂O is an arrhenius acid

Acid-base conjugate pairs differ by a single

• Electron

• Proton

• Neutron

• Oxygen

According to Arrhenius, what defines an acid?

• A substance that donates a hydrogen (H+) ion

• A substance that donates a hydroxide (OH-) ion

• A substance that produces hydrogen ions (H+) in solution

• A substance that produces hydroxide ions (OH-) in solution

Which of the following is a Bronsted-Lowry base?

• A substance that donates a proton

• A substance that accepts a proton

• A substance that produces hydrogen ions in solution

• A substance that produces hydroxide ions in solution

In the reaction @@ ext{NH}_3 + ext{H}_2 ext{O} ightarrow ext{NH}_4^+ + ext{OH}^-@@, identify the Bronsted-Lowry acid.
