Properties of Water and pH

Front

What are the properties of acids?

Back

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

Front

What is cohesion in relation to water?

Back

Cohesion is the property of water that allows molecules to stick to each other, leading to surface tension.

Front

What is adhesion in relation to water?

Back

Adhesion is the property of water that allows it to stick to other substances, which is important for processes like capillary action.

Front

What is capillary action?

Back

Capillary action is the ability of water to flow in narrow spaces without the assistance of external forces, often seen in plants.

Front

What is surface tension?

Back

Surface tension is the elastic tendency of a fluid surface that makes it acquire the least surface area possible, allowing small objects to float.

Front

What does pH measure?

Back

pH measures the concentration of hydrogen ions in a solution, indicating how acidic or basic it is.

Front

What is a base?

Back

A base is a substance that can accept hydrogen ions (protons) or donate electron pairs in reactions.

Front

What is an example of a common acid?

Back

Vinegar is a common acid, primarily composed of acetic acid.

Front

What is an example of a common base?

Back

Baking soda (sodium bicarbonate) is a common base.

Front

What happens to pH when an acid is added to water?

Back

The pH decreases, indicating an increase in hydrogen ion concentration.
