The Chemistry of Acids and Bases

What is the range of pH values in a basic/alkaline solution?

• 0-6

• 7.1-14

• 7

• 0-14

The range of pH values are 0-6.9 for

• Bases

• Acids

What is the pH of a neutral solution (like pure water)?

• 3

• 5

• 7

• 9

What does the pH scale measure?

• the weight of a liquid

• the density of a liquid

• the temperature of a liquid

• the acidity or alkalinity of a liquid

Water has a pH of 7. What is this substance on the pH scale?

• Acid

• Base

• Neutral

• Negative

Which ion determines a base?

• H⁺
• OH^-
• OH⁺
• CO_3^2-

In water, bases:

• are proton donors

• are proton acceptors

• produce H+

• produce water

In water, acids:

• produces OH-

• accepts H+ from another substance

• are proton donors

• are proton acceptors

Which ion determines an acid?

• H⁺

• OH^-

• OH⁺

• CO₃^2-

Solutions that have more OH– (hydroxide) ions than H+ (hydrogen) ions are

• acids

• bases

• enzymes

• neutral
