Question

Write a hypothesis about the pH level of common household solutions based on what you know about their physical and chemical properties. Use the format of "if . . . then . . . because . . .” and be sure to answer the lesson question "How is pH used to determine if a solution is acidic or basic?”

Answer 1

Sample Response: If a solution is an acid, then it will have a pH below 7, and if the solution is a base, it will have a pH above 7 since the pH value is determined by the concentration of H+ and OH– ions.

Answer 2

Sample Response: If a solution is an acid, then it will have a pH below 7, and if the solution is a base, it will have a pH above 7 since the pH value is determined by the concentration of H+ and OH– ions.

What did you include in your hypothesis? Check all that apply.

The “if” part of your hypothesis refers to the physical characteristics of the solution.

The “then” part of your hypothesis refers to a measurable difference in pH.

The “because” portion of your hypothesis connects the ideas of pH and H+ concentration.
