Solve problems and perform a first-hand investigation to use pH meters/probes and indicators to distinguish between acidic, basic and neutral chemicals

Acidic, basic and neutral chemicals can be distinguished between using the following simple procedure:

  • Obtain sample solutions to be tested.
  • Use a pH meter to measure the pH of the solutions.
  • A solution can be classified according to its pH:
    • Solutions with a pH less than 7 are acidic
    • Solutions with a pH of 7 are basic.
    • Solutions with a pH of greater than 7 are basic.
