What is an acid?

Back

An acid is a substance that donates protons (H+) in a chemical reaction and 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 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 is a neutralization reaction?

Back

A neutralization reaction is a chemical reaction between an acid and a base that produces water and a salt.

Front

What is a conjugate acid?

Back

A conjugate acid is the species formed when a base gains a proton (H+).

Front

What is a conjugate base?

Back

A conjugate base is the species that remains after an acid donates a proton (H+).

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 substances it interacts with, and is often involved in acid-base reactions.

Front

What is the most common acid found in nature?

Back

The most common acid found in nature is water (H2O).

Front

What is the hydronium ion?

Back

The hydronium ion (H3O+) is formed when an acid donates a proton to water, making it a key player in acid-base chemistry.

Front

What is the difference between strong and weak acids?

Back

Strong acids completely dissociate in water, while weak acids only partially dissociate.
