Acids and Bases

Front

What is the pH Scale?

Back

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

Front

Where are the strongest acids found on the pH Scale?

Back

The strongest acids are found on the left end of the pH Scale, with values ranging from 0 to 6.

Front

Where are the strongest bases found on the pH Scale?

Back

The strongest bases are found on the right end of the pH Scale, with values ranging from 8 to 14.

Front

What is an acid?

Back

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

Front

What is a base?

Back

A base is a substance that accepts hydrogen ions (H+) in a solution and has 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 the Universal Indicator?

Back

The Universal Indicator is a chemical that changes color in response to the pH level of a solution, helping to identify whether it is acidic, neutral, or basic.

Front

What pH range indicates an acidic solution?

Back

An acidic solution has a pH range of 0 to 6.

Front

What pH range indicates a basic solution?

Back

A basic solution has a pH range of 8 to 14.

Front

What happens to the color of the Universal Indicator in an acid?

Back

In an acid, the Universal Indicator typically turns red or orange.
