Acids and Bases

Front

What is an acid?

Back

An acid is a substance that donates hydrogen ions (H+) in a solution, resulting in a pH less than 7.

Front

What is a base?

Back

A base is a substance that accepts hydrogen ions (H+) or donates hydroxide ions (OH-) in a solution, resulting in a pH greater than 7.

Front

What does pH measure?

Back

pH measures the concentration of hydrogen ions (H+) in a solution.

Front

What is the pH range for acids?

Back

The pH range for acids is from 0 to 6.9.

Front

What is the pH range for bases?

Back

The pH range for bases is from 7.1 to 14.

Front

What is a neutral solution?

Back

A neutral solution has a pH of 7, indicating equal concentrations of hydrogen ions (H+) and hydroxide ions (OH-).

Front

What happens when an acid is dissolved in water?

Back

When an acid is dissolved in water, it produces hydrogen ions (H+).

Front

What happens when a base is dissolved in water?

Back

When a base is dissolved in water, it produces hydroxide ions (OH-).

Front

What is a strong acid?

Back

A strong acid is an acid that completely dissociates in water, producing a high concentration of hydrogen ions.

Front

What is a weak acid?

Back

A weak acid is an acid that partially dissociates in water, resulting in a lower concentration of hydrogen ions.
