Acids and Bases Review

Front

What is an acid?

Back

An acid is a substance that donates protons (H+) in a chemical reaction and typically has a pH less than 7.

Front

What is a base?

Back

A base is a substance that accepts protons (H+) or donates hydroxide ions (OH-) in a chemical reaction and typically has a pH greater than 7.

Front

What is the pH scale?

Back

The pH scale measures the acidity or basicity of a solution, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

What does it mean if a solution has a pH below 7?

Back

A solution with a pH below 7 is considered acidic.

Front

What does it mean if a solution has a pH above 7?

Back

A solution with a pH above 7 is considered basic.

Front

What is an example of a strong acid?

Back

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

Front

What is an example of a strong base?

Back

Sodium hydroxide (NaOH) is an example of a strong base.

Front

What is the Bronsted-Lowry theory?

Back

The Bronsted-Lowry theory defines acids as proton donors and bases as proton acceptors.

Front

What does amphoteric mean?

Back

Amphoteric substances can act as both acids and bases, depending on the reaction.

Front

What is a conjugate acid?

Back

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