Open Ended

What questions do you still have about acids, bases, or the concept of pH after this lesson?

Multiple Choice

How does the difference in pH between two solutions help you determine whether they are acidic or basic?

• A lower pH indicates a basic solution, and a higher pH indicates an acidic solution.

• A lower pH indicates an acidic solution, and a higher pH indicates a basic solution.

• Both acidic and basic solutions have the same pH.

• pH does not help in determining if a solution is acidic or basic.
