pH and Its Properties

The more hydrogen ions present, the lower the pH, making the solution more ______.

What is the pH range for acids and bases?

• Below 7 for acids and above 7 for bases

• Above 7 for acids and below 7 for bases

• Exactly 7 for both acids and bases

• Between 0 and 14 for both acids and bases

The conductivity of a solution is related to the presence of ___ ions, including hydrogen ions.

What does pH measure?

• Temperature

• Pressure

• Acidity or basicity of a solution

• Volume

How do hydrogen ions influence the pH of a solution?

What do acids and bases do in terms of hydrogen ions?

• Acids donate hydrogen ions and bases accept hydrogen ions.

• Acids accept hydrogen ions and bases donate hydrogen ions.

• Acids and bases both donate hydrogen ions.

• Acids and bases both accept hydrogen ions.

How does the pH scale determine whether a substance is neutral, acidic, or basic?
