Acids, Bases, and the pH Scale Practice

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 happens to the pH of a solution when OH- ions are added?

Back

The pH of the solution increases (goes up) because OH- ions make the solution more basic.

Front

What are the products of a neutralization reaction between an acid and a base?

Back

The products are water and a salt.

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

Lithium hydroxide (LiOH) is an example of a strong base.

Front

What does a pH greater than 7 indicate?

Back

A pH greater than 7 indicates a basic (alkaline) solution.

Front

What does a pH less than 7 indicate?

Back

A pH less than 7 indicates an acidic solution.

Front

What is the relationship between acids and hydrogen ions (H+)?

Back

Acids release hydrogen ions (H+) when dissolved in water.

Front

What is the relationship between bases and hydroxide ions (OH-)?

Back

Bases release hydroxide ions (OH-) when dissolved in water.

Front

What is a neutral solution?

Back

A neutral solution has a pH of 7, meaning it is neither acidic nor basic.
