Acid-Base Theories

NaOH is:

• an Arrhenius base

• an Arrhenius acid

• neither an acid nor a base

• both an acid and a base

An Arrhenius base:

• donates H+

• accepts H+

• produces H+

• produces OH-

An Arrhenius acid:

• donates H+ to another substance

• accepts H+ from another substance

• produces H+

• produces OH-

A hydrogen ion, H⁺, is the same as a(n):

• neutron
• electron
• proton
• hydroxide ion

Forms a OH- hydroxide ion

• Lewis Base
• Arrhenius Base
• Bronsted Lowry Base
• Bronsted Lowry Acid

Which of the following is a hydronium ion?

• H⁺

• H₂O

• OH^–

• H₃O⁺

NH₃ is:

• a Bronsted Lowry base

• an Arrhenius base

• an acid

• both an Arrhenius and a Bronsted Lowry base

Which substance is an Arrhenius base

• KCl

• CH₃Cl

• KOH

• CH₃OH

One alternate acid-base theory states that an acid is an

• H⁺ donor

• H⁺ acceptor

• OH^- donor

• OH^- acceptor

According to one acid-base theory, a water molecule acts as a base when the water molecule

• H⁺ donor

• H⁺ acceptor

• OH^- donor

• OH^- acceptor
