Unit 4 - AP Chemistry

Front

What is the definition of an acid?

Back

An acid is defined as a proton donor.

Front

What is the definition of a base?

Back

A base is defined as a proton acceptor.

Front

In the reaction H⁺ + H₂O → H₃O⁺, what role does water play?

Back

Water acts as a base accepting a proton.

Front

What is a conjugate acid-base pair?

Back

A conjugate acid-base pair consists of two species that differ by the presence of a proton.

Front

Identify the species reduced in the reaction: Fe_(s) + 2 Ag⁺_(aq) → Fe²⁺_(aq) + 2 Ag_(s).

Back

The species reduced is Ag.

Front

What happens to the strength of a conjugate base as the strength of its acid increases?

Back

The stronger the acid, the weaker its conjugate base.

Front

What is the role of H₃O⁺ in acid-base reactions?

Back

H₃O⁺ acts as an acid donating a proton.

Front

What is the difference between a strong acid and a weak acid?

Back

A strong acid completely dissociates in solution, while a weak acid only partially dissociates.

Front

Provide an example of a strong acid.

Back

Hydrochloric acid (HCl) is an example of a strong acid.

Front

Provide an example of a weak acid.

Back

Acetic acid (CH₃COOH) is an example of a weak acid.
