Acids and Bases

Front

What is the pH scale?

Back

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

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 is the significance of a pH value of 7?

Back

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

Front

What are common examples of acids?

Back

Common examples of acids include vinegar (acetic acid), lemon juice (citric acid), and hydrochloric acid.

Front

What are common examples of bases?

Back

Common examples of bases include baking soda (sodium bicarbonate), soap, and bleach.

Front

What is the relationship between acids and hydrogen ions?

Back

Acids increase the concentration of hydrogen ions (H+) in a solution.

Front

What is the relationship between bases and hydroxide ions?

Back

Bases increase the concentration of hydroxide ions (OH-) in a solution.

Front

What is a neutralization reaction?

Back

A neutralization reaction occurs when an acid reacts with a base to produce water and a salt.

Front

What are the properties of acids?

Back

Acids taste sour, conduct electricity when dissolved in water, and react with metals to produce hydrogen gas.
