8.1 Acids and Bases

Question 1

Arrhenius Theory

Answer 1

Theory stating that, in an aqueous solution, an acid is a substance that produces hydrogen ions and a base is a substance that produces hydroxide ions

Question 2

Bronsted-Lowry Theory

Answer 2

Theory stating that an acid is a hydrogen ion (proton) donor and a base is a hydrogen ion (proton) acceptor

Question 3

Hydronium ion

Answer 3

Water molecule that has accepted a hydrogen ion, H3O+

Question 4

Conjugate acid

Answer 4

Substance that forms when a base, according to the Bronsted-Lowry theory, accepts a hydrogen ion (proton)

Question 5

Conjugate base

Answer 5

Substance that forms when an acid loses a hydrogen ion (proton)

Question 6

Conjugate acid-base pair

Answer 6

Two substances related to each oter by donating/accepting of a single hydrogen ion.

Question 7

Amphiprotic (amphoteric)

Answer 7

Able to donate or accept a hydrogen ion (proton) and thus act as both a Bronsted-Lowry acid and a Bronsted-Lowry base

Question 8

Acid ionization constant (Ka)

Answer 8

EQ constant for ionization of an acid; also called acid dissassociation constant
