What is the pH scale?

Back

The pH scale is a measure of how acidic or basic a solution is, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

What is an acid?

Back

An acid is a substance that releases H+ ions in solution, resulting in a pH less than 7.

Front

What is a base?

Back

A base is a substance that releases OH- ions in solution, resulting in a pH greater than 7.

Front

What is a neutral solution?

Back

A neutral solution has a pH of 7, meaning it is neither acidic nor 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 does it mean if a solution has a pH of 3?

Back

A solution with a pH of 3 is considered acidic.

Front

What does it mean if a solution has a pH of 10?

Back

A solution with a pH of 10 is considered basic.

Front

What is the role of buffers in solutions?

Back

Buffers help maintain a stable pH in a solution by neutralizing small amounts of acids or bases.

What is the pH of pure water?

Back

The pH of pure water is 7, which is neutral.
