Acids and Bases

Front

What is an acid?

Back

An acid is a substance that donates protons (H+) in a chemical reaction. Acids typically have a sour taste and can turn blue litmus paper red.

Front

What is a base?

Back

A base is a substance that accepts protons (H+) or donates hydroxide ions (OH-) in a chemical reaction. Bases usually have a bitter taste and can turn red litmus paper blue.

Front

What is pH?

Back

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

Front

What is litmus paper used for?

Back

Litmus paper is used to test the acidity or basicity of a solution. It changes color depending on the pH of the solution.

Front

What happens when an acid and a base react?

Back

When an acid and a base react, they neutralize each other, typically producing water and a salt.

Front

What is a neutral solution?

Back

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

Front

Can acids conduct electricity?

Back

Yes, acids can conduct electricity because they dissociate into ions when dissolved in water.

Front

Can bases conduct electricity?

Back

Yes, bases can also conduct electricity as they dissociate into ions when dissolved in water.

Front

What is an example of a common acid?

Back

An example of a common acid is citric acid, found in citrus fruits like lemons and oranges.

Front

What is an example of a common base?

Back

An example of a common base is sodium bicarbonate (baking soda), which is used in cooking.
