Unit 4 - AP Chemistry

Front

What is a precipitation reaction?

Back

A precipitation reaction is a chemical reaction in which two aqueous solutions react to form an insoluble solid, known as a precipitate.

Front

What happens to the species that is reduced in a redox reaction?

Back

The species that is reduced gains electrons, becoming more negatively charged.

Front

Identify a conjugate acid-base pair in the reaction: CH₃CH₂COOH(aq) + H₂O(l) ⇄ CH₃CH₂COO⁻(aq) + H₃O⁺(aq).

Back

The conjugate acid-base pair is CH₃CH₂COOH(aq) and CH₃CH₂COO⁻(aq).

Front

What is the conjugate base of H₂SO₄?

Back

The conjugate base of H₂SO₄ is HSO₄⁻.

Front

How is an acid defined in chemistry?

Back

An acid is defined as a proton donor.

Front

What is a redox reaction?

Back

A redox reaction is a chemical reaction that involves the transfer of electrons between two species, resulting in changes in oxidation states.

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

What is the role of water in acid-base reactions?

Back

Water can act as both an acid and a base, depending on the reaction, facilitating proton transfer.

Front

Define a conjugate acid.

Back

A conjugate acid is the species formed when a base gains a proton.

Front

Define a conjugate base.

Back

A conjugate base is the species that remains after an acid donates a proton.
