Changing pH Investigation III

Testing the pH of different kinds of leaves

  1. Obtain a small plastic bag. Place a small amount of water in the bag. Tear one type of leaf into small pieces. Seal the bag and carefully crush the leaves into the water. Continue crushing the leaves for 5 minutes being careful not to tear the bag.

  2. Test the pH of the leafy solution by using the pH probe. Refer to Technical Hints to see how to use the DataLogger software to measure pH. Record the names and pH of the leaf in your spreadsheet. Refer to Technical Hints to see how to transfer data to the spreadsheet.



  3. Repeat the process for the remaining two types of leaves that you selected. Record their pH on the spreadsheet.

  4. Answer Question 5 in "Analysis".
