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?”

If a solution has a pH level lower than 7, then it is acidic because pH is used to measure the concentration of hydrogen ions in a solution, and a lower pH indicates a higher concentration of hydrogen ions, which makes the solution acidic.
